NEW Brembo Racing system for the Nissan GT-R (R35)

New Brembo Racing system for the CBRD Speed Factory Nissan GT-R (R35).

This is a direct replacement for the front Brembo O.E. (Original Equipment) system which is already an extremely capable system, but this system is meant for environments with heavy brake demand.

The brake system is comprised of a lightweight Brembo Racing XB105 4-piston billet caliper, 25mm pad vs. 18.5mm (increased thermal resistance), and 2-piece, 380×34 type 3 discs that fit under the *OE wheels. ‪

Ferrari 458 “Street Challenge” 90 LBS Weight reduction

SHAVING OVER 90 POUNDS OFF A FERRARI 458:

BBi Autosport, an authorized Sabelt dealer, and one of the leading performance shops in Southern California, shaved over 90 pounds from a Ferrari 458 Italia. That is a significant weight savings that was achieved simply by changing out the OE seats to Sabelt carbon seats (Sabelt is also the OE supplier to Ferrari). The 562 horsepower 458 Italia is Ferrari’s primary high performance mid-engine V8 sports car sold worldwide and also the current platform homologated by Michelloto which is the racing arm for all Ferrari GT programs for professional sports car racing worldwide.

BENEFITS OF A FULL BUCKET SEAT:

A non-reclinable full bucket racing seat offers greater driver support and confidence (helps against lateral G forces while potentially lowering the center-of-gravity) during track and high performance use. This allows the driver to focus on  steering inputs rather than  bracing themselves in their less supportive OEM seat. A racing seat is designed to limit body movement when properly fitted to the driver vs. OEM seats which are designed for general comfort and ease of entry/exit for a wide range of body types. FIA approved, full bucket, racing seats  also have provisions for racing harnesses, which offer a much higher level of safety and protection in the case of an accident or impact.


INGREDIENTS REQUIRED:

  • Ferrari 458 Italia
  • BBi Autosport
  • Sabelt GT-600 Dry Carbon full bucket seats and side mounts
  • Sabelt light weight Harnesses
  • Seat mounting base (supplied by BBi Autosport)
  • Harness mounting (supplied by BBi Autosport)

Sabelt (part of the Brembo group) is a technology leader in safety equipment and a technical supplier to Ferrari on several OE and motorsport programs.  Sabelt produces the optional high performance seat options for the OE Ferrari 458 Italia and also supplies FIA approved* carbon racing seats into the Ferrari “Challenge” and GT3 customer racing programs.

*What exactly does FIA Approved mean?

Safety equipment which is FIA approved is rigorously tested and conforms to the same high safety standards which over 30 different motorsports series worldwide including Formula 1 conform to. Formed over 100 years ago in 1904, the FIA (Federation Internationale de I’Automobile) is a foundation which governs and regulates most aspects (including safety) of the top professional motorsports series worldwide. All of the current Sabelt racing seats are FIA approved.

Reducing weight from the 3,280 pound (curb weight) Ferrari 458 Italia, a high performance platform already engineered using some of the lightest composites and materials on the market derived from Ferrari’s extensive background in motorsport, is not an easy job. It is made easier however when the right technical partners, suppliers and know how is involved.

SEAT COMPARISON:

The Sabelt seats chosen for the Ferrari 458 “Street Challenge” project are Sabelt carbon full bucket racing seats (based off the Sabelt GT-600 carbon seat) supplied for the Ferrari “Challenge” series. The GT-600 is one of Sabelt’s lightest carbon seats, and has several key features which make it a great option for safety and comfort.

  • Construction: Carbon for maximum weight savings.
  • Safety: GT-600 is HANS Device compatible for motorsports use
  • Ergonomic Cushion: One piece base to backrest cushion constructed from double density memory form foam helps maximize driver lumbar support and comfort.
  • Horizontal Seams: Reduces back perspiration by increasing the circulation of air.
  • Range: Sabelt provides a range of different seat sizes (M, L, XL) to maximize fitment and comfort.*
    *NOTE: as a more cost effective solution, the Sabelt GT-140 seat can also be used. It utilizes fiberglass instead of a carbon shell.

With any full bucket seat designed for professional racing, one does lose the functionality of the OE nature, comfort and recline-able nature of the standard OE seat. Bucket seats designed for racing are designed for maximum ergonomic comfort and protection in high performance or racing use.

MAKING IT ALL WORK TOGETHER:

To install the Sabelt seats and belts, BBi had a seat base manufactured specifically for the Sabelt side mounts and sliders to fit into the Ferrari 458. Without a vehicle specific seat base, it is impossible to install slider equipped seats in a car.

SABELT 6 POINT HARNESS:

The Sabelt harnesses selected for this Ferrari 458 “Street Challenge” project are FIA Approved 6-point harnesses using Sabelt’s famous cam lock (rotary buckle) and lightweight aluminum quick adjusters. These harnesses share components that would be used in a custom harness for a Ferrari 458 GT3 or Challenge car homologated for professional racing. Some of the main key features of the Sabelt harnesses are:

– Ease of Use: Sabelt’s lightweight aluminum quick adjusters were developed to require less load on the lever, which results in an easy, fast, and fluid adjustment. In addition endurance racing where quick driver changes are critical, these have been the popular choice of top level teams and track day / club racing customers. Confidence in a properly tightened harness is important in any form of racing.
– Safety and development: Sabelt’s cam lock design has continued to set them apart in the safety industry. Since it’s introduction in 1976, Sabelt has continued to put engineering resources into the development and weight reduction of their cam locks (as well as all hardware pieces). This has been accomplished with in house manufacturing, testing, and working closely with FIA.

Sabelt cam lock.

Sabelt camlock.

The material used on the release lever and on the body of the cam lock is aluminum alloy (no plastic). Sabelt continues to use aluminum for a better heat / flame resistance. Even without the use of plastic, Sabelt has still been able to a produce some of the lightest weight and most functionally advance cam locks on the market.
– Range / Options: Sabelt harnesses are available in a wide range of configurations to suit driver preference and applications. Some of the standard options for FIA approved belts include 4 or 6 point configuration, full 3” or 3-2” Hans friendly shoulder straps, aluminum or steel adjusters, 2 or 3 inch lap belts, “pull up” or “pull down lap belt adjustment, and snap hook (eye-bolt type) or bolt in configurations with the ability for the shoulder straps to wrap around a harness bar.

Improving driver safety is always a primary concern for auto manufacturers, high performance shops and professional racing teams regardless of street, track or race use. With the many years of experience in safety and professional racing with Ferrari, using Sabelt safety equipment was BBi Autosport’s preferred choice on project: Ferrari 458 “Street Challenge”.

Brembo 2-piece disc, brake fluid, and pad install on GMG Racing’s 991 GT3

GMG Racing 991 GT3 – Brembo Performance Install & Review

GMG Racing, an Official Brembo dealer, is one of the premier high performance and professional racing shops in Southern California who specialize in Porsche track preparation. GMG Racing’s background in professional racing campaigning multi-car efforts in the Pirelli World Challenge series with both Porsche and Audi FIA GT3 platforms. Using this extensive racing experience accumulated over the years, GMG Racing also offers up the same upgrades supplied by their technical partners that they trust on the racetrack.

James Sofronas, owner driver of GMG Racing, also owns a personal 991 GT3 shop car to showcase GMG’s capabilities on and off the track. One such way is by holding track day and driver training specifically for 991 GT3 owners at The Thermal Club raceway which is very demanding on brakes and tires.

One of the first major upgrades done to the GMG Racing’s 991 “WC-GT3” was improve the braking reliability, longevity, and performance under track use. GMG Racing swapped out the Porsche OE discs, pads and fluid on the 991 GT3 with Brembo 2-piece discs, Race Technologies pads, and Brembo Racing HTC64T fluid.

GMG Racing 991

GMG Racing 991 “WC-GT3”

INGREDIENTS REQUIRED:

  • Porsche 991 GT3
  • GMG Racing
  • Brembo 2-piece front disc assemblies.
  • Brembo 2-piece rear disc assemblies
  • Your choice of front and rear pads although Race Technologies TS20’s were used.
  • 6 bottles of Brembo HTC64T Racing brake fluid.
  • Tarett Engineering brake caliper studs (*optional, supplied by GMG Racing)

BRAKE DISC COMPARISON

While the 991 GT3 has very sophisticated brakes for an OE brake package, there is always more that can be done with certain components to improve overall longevity and performance. The OE Porsche brake discs, pads and fluid are all engineered with comfort, serviceability and cost effectiveness in mind.

Brembo OE co-cast discs

Brembo OE co-cast discs

As the braking system’s primary function is to dissipate heat, Brembo uses purpose-designed discs in order to increase the fade resistance and thermal capacity of the system. These discs are directionally ventilated for enhanced cooling and slotted for better performance and continuously refreshing the pad surface. Brembo 2-piece discs are made up of a proprietary advanced cast-iron alloy which offers an exceptional coefficient of friction and resistance to thermal shock and fatigue.

The same Brembo Racing discs trusted every weekend in professional motorsports are also utilized in the Brembo Performance program (GT, GT-R & club race systems).

The OE 991 GT3 co-cast Brembo discs are sized 380 x 34 mm in the front and weigh 24 lbs, and 380 x 30 mm in the rear weighing at 23.4 lbs. The Brembo Racing Heavy Duty “HD” type V front disc assemblies are 24.5 lbs, and the rear Type III assemblies are 22 lbs. The 991 Turbo discs are substantially heavier than the GT3 discs as the Turbo models are harder on front brakes than the GT3 models. Brembo 2-piece disc assemblies on a 991 GT3 or Turbo will offer a net gain in weight savings.

Brembo Porsche OE discs vs Brembo Performance 2-piece disc assemblies

There are many advantages to replacing the OE discs on a Porsche GT3 or Turbo, some of them are:

  • OEM Integration: Brembo upgrades are designed to work seamlessly with the OE Master, ABS and existing brake systems (Example: Integration with the rear parking brake)
  • Weight Savings: Reducing overall un-sprung weight helps improve vehicle dynamics such as handling, braking, and acceleration.
  • Durability: The Brembo discs for these Porsche disc assemblies come from the Brembo Racing program. These discs feature proprietary metallurgy which is resistant to fatigue, cracking, and are engineered for maximum longevity on the street or track.
  • Different Slot Types: Extensively used in professional motorsports, Brembo type III and type V disc face types can be used to tune or adjust the brakes’ technical characteristics to the chassis or driver.
  • Range: Brembo offers lightweight and heavy duty “HD” disc options to suit the needs of the driver, car model (Turbo or GT3) /setup and environment.
  • Replacements: Brembo replacement rings are comparably priced to OE, and when the Brembo discs are worn, only the outer disc ring and hardware needs to be replaced.
  • Drivability: Brembo 2-piece discs maintain the drivability of the OE brakes by using anti-rattle hardware. Brembo’s specific anti-rattle disc hardware utilizes a spring fastener in order to slightly preload the assembly which eliminates the noise (clattering) generally associated with floating discs.

NOTE: Brembo’s specific anti-rattle hardware which is commonly used in high performance brake disc assemblies was actually developed in the 1990s. This innovation was initially engineered exclusively for the McLaren F1 supercar which is why the hardware is often nicknamed the “McLaren” spring.

 BRAKE DISC INSTALLATION

GMG technicians Ruben and Sergei (who drives a 997 Turbo himself) used their extensive Porsche know how to install the Brembo 2 piece disc assemblies on the GMG 991 GT3 shop car.

 FRONT DISC ASSEMBLIES

The OE front discs were the first to be installed. The Brembo performance 2-piece discs and Race Technologies pads are a direct replacement to the OE units. GMG made sure to push the pistons all the way back in to ensure proper stack width (2 pads and brake rotor total width). The Porsche center lock “lug” was then removed and the Brembo 2-piece disc assembly and pads were then installed. Once the Brembo performance disc assemblies were fitted, the OE Caliper was re-installed using brand new caliper studs. The entire process was done on the front right disc, and then the front left disc.

Since the GMG Shop car is also their test car, the car will see extended track time on many southern California circuits. A Brembo Type V 380 x 34 mm front disc was specified for the lowest disc and pad wear under heavy track conditions. An optional Race Technologies endurance compound was also supplied for dedicated track use.

  • Brembo Type V (endurance face type): motorsport developed face type with marginally less initial response compared to the type III face type. The Brembo Racing type V face type was also designed to have lower pad and disc wear for certain long distance endurance races (mostly 10, 12 and 24 hour races).

REAR DISC ASSEMBLIES

Once the front disc assemblies were installed, GMG then turned their attention to the rear discs and pads. The exact same installation procedure was followed for the rear disc assemblies as well. The rear right corner was installed first, and then the rear left corner was installed. GMG installed new caliper studs on the rear as well when re-installing the OE Porsche calipers. Race Technologies TS20 compound pads were used for the rears as the baseline pad.

The Brembo Type III 380 x 30 mm rear brake disc was specified for optimum balance and brake release under heavy track conditions. This is because the 991 GT3 shifts its’ brake balance towards the rear under braking. The smooth release characteristics of the Brembo Type III face type can help a driver avoid rear tire in stop lock up while still maintaining optimum braking performance.

  • Brembo Type III (aggressive face type): motorsport developed face type with an emphasis on high initial response while maintaining a smooth pedal release.

As mentioned earlier in this article, the Brembo 2-piece disc assemblies are compatible with the Porsche factory parking brake. One does not have to compromise and lose the parking brake functionality when installing the Brembo disc assemblies.

BRAKE FLUID AND BLEED

Upgrading brake fluid for spirited, track or racing use is easily one of the most overlooked things when thinking of upgrading any component or part of the brake system. Brembo’s HTC64T brake fluid is the top fluid used in the top professional racing categories around the world (Examples: F1, FIA GT, LMP1). This is because the Brembo fluid offers low compressibility, good after boil recovery, and high boiling points.

  • Brembo HTC64T Typical Applications: Open Wheel*, Stock Car, Rally, Endurance & Sprint GT**, Track Day.

*Brembo HTC64T is one of a very few select fluids being actively used by F1 teams.

**Brembo HTC64T and LCF600 Plus are both racing brake fluids which are actively used and homologated for FIA GT3 & GTE based sports-car racing.

  • Independently proven low Compressibility at severe temperatures.
  • Dry Boiling Point: 335 C (635 F)
  • Racing Use Only
Brembo HTC64T

Brake fluid performs a very critical function as it is the “life blood” of the brake system, as it is the foundation to hydraulically transfer brake pedal effort to the brake caliper’s pistons. Brake fluid also performs a vital function of lubricating caliper piston seals brake fluid performance (or the lack of) can directly affect brake pedal feel, pressure and consistency through the operating temperature range. It is also one the most cost effective ways to improve brake pedal consistency (avoiding spongy pedal) under high temperature use.

Once the Brembo performance 2-piece disc assemblies and RT pads were installed on all four corners, the OEM brake fluid was flushed and bled with Brembo Racing HTC64T brake fluid. As the fluid was being bled on each corner, GMG made sure to keep an ample amount of new fluid filled in the master cylinder reservoir to ensure that air did not enter into the hydraulic system.

ON TRACK IMPRESSIONS

To evaluate the results of the new Brembo discs, fluid bleed, and RT pads, the GMG Team took the 991 GT3 shop car to Thermal Club.

Driver (James Sofronas) and GMG Team comments: Testing out a new setup @thethermalclub today! @jamessofronas had the GMG 991 GT3 out and with the new Brembo Brake pad and Rotor setup says that the car is even more amazing! A predictable pedal feel without activating the ABS too early. A must have for any car that is going to see some track time! Combined with Pirelli Trofeo R tires it is just a winning combo!

Thermal Club Track layout. Image: Thermal Club

Thermal Club Track layout. Image: Thermal Club

Thermal Club located in Palm Springs, California often has very high ambient temperatures which can be demanding on the car, tires, and brakes. The effectiveness of brake cooling is only as good as the temperature of the air flowing thru the brake ducts (if the ambient air is hotter, the brakes will not cool down as much). The track layout and surface can be very similar to some of the European GT tracks, featuring many high speed to low speed braking zones, and a high level of mechanical grip (the more grip you have, the harder you can brake). GMG Racing has setup their shop GT3 understanding the demands of the various tracks around Southern California, and the Porsche 991 GT3, for optimal results.

Modern sports cars have very sophisticated OE ABS systems and engaging the ABS under braking can lead to poor threshold braking, lack of pedal feel, and potentially result in a slower lap time. Having a high overall level of braking confidence and control, usually allows the driver to spend less time on the brake pedal. If the brakes offer enough performance and control for the driver to stay out of ABS engagement (depending on their driving style and car setup), the result is usually a faster lap time on track.

PORSCHE 911 GT3 (997): BREMBO 2-PIECE TY3 DISCS

PORSCHE 911 GT3 & TURBO (997): BREMBO 2-PIECE TY3 DISCS

10380480_725113257553163_293994279633568863_o

Porsche’s 911 (997) GT3 and Turbo are platforms engineered specifically for high performance use, which also have unique brake demands. (Example: 450 horsepower for a 3.8 GT3 RS and 500 horsepower for a 4.0 GT3 RS)

The Brembo OE brakes equipped on the specific Porsche 997 GT3 & Turbo models are a sophisticated design for an OE application. The Porsche Brembo OE brakes utilize 6-piston aluminum fixed monobloc calipers front and 4-piston aluminum fixed monobloc calipers rear. The brake discs are heavy duty 380 x 34 mm ventilated front and 350 x 28 mm rear brake discs. While 997 GT3 and Turbo brakes physically look similar, their piston configuration and brake balance are tuned for the specific chassis. The GT3 places more of the brake balance towards the rear, while the Turbo is more demanding on the front brakes due to the AWD (All Wheel Drive) system and electronic aids.

The Porsche 911 GT3 OE brakes use a wide annulus (radial depth) front and rear for maximum pad swept area (this makes a significant difference in thermal capacity and pad life). The OE pads are also 18.5 mm thick front and rear which is comparable to most high performance aftermarket calipers.

There are certain limitations with the OE components on any high performance application as they are designed specifically for the car manufacturers to their requirements of comfort, wear rates in various road environments, cost, and serviceability.

As the braking system’s primary function is to dissipate heat, Brembo uses purpose-designed discs in order to increase the fade resistance and thermal capacity of the system. These Brembo Racing discs are directionally ventilated for enhanced cooling and slotted for better performance and continuously refreshing the pad surface. Brembo 2-piece discs are made up of a proprietary advanced cast-iron alloy which offers an exceptional coefficient of friction and resistance to thermal shock and fatigue.

The same Brembo Racing discs trusted every weekend in professional motorsports are also utilized in the Brembo Performance program (GT, GT|R, & Race Systems).

“At Olsen Motorsports we only use the best, most reliable components on the market. Brembo has come to the table with a complete package that has changed the way we think about brakes. With the many options in friction we are able to put together track specific brake packages to get the last bit of pace out of the many chassis’ s that we work with to stay consistent, competitive, and up front on track. The longevity and consistency of the product is amazing, and that coupled with the accessibility, knowledge, and support of the factory, Brembo is now the only brand that we offer to our customers”.

Tim Olsen, owner of Olsen Motorsports

“Ok, here‘s a factual event that happened to us, it was very eye opening to me at the time, I thought “this cannot be possible”, but it was because we did a back to back test later that morning and sure enough, it fixed the problem (this was at a Sebring test in February, the weather was mid 70’s to low 80’s).  The driver complained of poor threshold feel, we replaced the pads thinking they had lost their friction potential, still the same result. So then we changed rotors (thinking “this is insane but what the hell”), and on the second lap the driver called in saying “I can brake properly now”.  I learned a lot that day, to never be closed minded about things that otherwise seem obvious.

 Brembo rotors, combined with the correct pads, allow the driver to decelerate the car harder and more controllably because the materials are properly compatible – this is not case with other rotors and pads and we know this because we did back to back tests, the drivers response and the data proved it”

Craig Watkins, former Engineer of Flying Lizard Motorsports for 10+ years

“Although often overlooked, the ability to stop is really the most important aspect of sports car racing.  As a driver, I have been trusting Brembo products to slow me down for the majority of my career.  I am very demanding of the brake system on my race cars.  I need stability at the initial brake application, and the ability to modulate smoothly off the brake pedal is essential for optimizing corner speeds.  Having Brembo components installed on the car always gives me the confidence to push the limits throughout the brake zones.”

” In fact, it was Brembo products on the Brumos Racing Porsche that helped us make that final charge for the 2011 Rolex Series Championship.  A qualifying issue in the final race placed us at the back of the grid, and it wouldn’t have been possible to make our way up to the front without maximizing stopping capacity.”

Brembo Carbon Materials (CCM, CCM-R, and Racing Carbon)

Brembo Carbon Materials (CCM, CCM-R, and racing carbon)

 

Brembo Offers 3 Types of Carbon Based Discs:

  1. Carbon Ceramic (CCM): street use
  2. Carbon Ceramic (CCM-R): street and track use
  3. Carbon-Carbon: race use

Original Equipment Carbon Ceramic Material (CCM):

CCM discs supplied for the OEM are designed to offer significant weight savings over typical cast iron OEM discs while offering outstanding performance and very long life under typical street use. However, OEM CCM discs have limitations for serious performance driving and dedicated track use.

Carbon ceramic offers significant weight savings over typical cast iron OEM discs

OEM CCM discs do not wear in the same way as cast iron discs. The life on CCM discs is determined by the loss of disc mass as the material oxidizes. This cannot be verified by simply measuring the overall disc thickness like traditional iron discs. Each disc assembly is weighed after assembly and then the minimum allowable weight is permanently etched into the bell. In order to check the weight after use, a cleaning procedure must be performed before checking the weight.

An exhaustive on-road and on-track test program is needed during vehicle development in order to manage airflow to the discs in order to provide enough cooling to achieve satisfactory component life. Oxidation increases rapidly with temperature and it is for this reason that extended high temperature use such as experienced on the race track dramatically reduces the discs life.

OEM carbon ceramic (CCM)

OEM CCM discs are designed to be used with very specific brake pad materials. While there are other pad materials supplied on the market by various pad manufacturers claiming to be “CCM friendly”, there is currently no established validation process for such materials. Pad materials developed for cast iron brake discs will have considerably different results when used on CCM if the various factors are not considered. Pads used with CCM discs also have much greater surface area than would be present in a similar performing cast-iron system which somewhat offsets the weight savings of the disc.

  • Production Process Time: Relatively quick production time (for a carbon-based material), approximately 4 weeks (1 month).

Brembo Racing Carbon-Carbon:

Brembo carbon-carbon materials are used in the top levels of professional motorsports in such racing categories as open wheel (i.e. Formula 1 and IndyCar) and sportscar racing (i.e. LeMans and LMP1) amongst others. The latest motorsport carbon-carbon discs offer stable performance over a wide temperature range, are extremely lightweight, and are highly wear resistant.

While many companies market high performance and racing carbon materials, there are only a few manufacturers who sell carbon-carbon brake materials to the top levels of professional motorsports. These are: Brembo, Carbone Industrie, and Hitco (a subsidiary of the Brembo SGL Group). Brembo supplied over 60% of the Formula 1 field in 2014 and is the sole supplier for IndyCar, Along with supplying brake systems to both factory run Porsche and Audi LMP1 efforts in the FIA WEC (World Endurance Championship) for 2015. It is quite normal for an LMP1 car racing at the 24 hours of LeMans to finish the endurance race without any disc or pad change.

Racing carbon-carbon systems differ from other brake systems in that they utilize a pad that is also made of carbon-carbon material very similar to the disc material. There are specific carbon-carbon formulations for the disc and pads that can be chosen to suit the system to the needs of the racing series, car, track, or driver.

Wear occurs in a carbon-carbon system both through material thickness reduction, as well as by oxidation. During a braking event, the temperatures reached in a carbon-carbon system can be well in excess of those seen in a racing cast-iron system, but the airflow management must be such that the temperatures are brought down significantly to avoid excessive oxidation. Racing carbon-carbon systems do not work well at low temperatures, and are for motorsports use only.

  • Production Process Time: Approximately 28 weeks (7 months) for production from start to finish.

Brembo CCM-R:

Brembo created the CCM-R material by applying the knowledge gained through developing and supplying carbon-based brake materials for both OEM road use and racing applications. Brembo CCM-R discs are sized and cross-drilled similar to the OEM CCM material discs, however, the base material, production process and construction is more in-line with Brembo carbon-carbon racing discs. CCM-R discs were developed with high-performance and racing use in mind.


Debut of CCM-R for the Nissan GT-R (R35)

Brembo CCM-R material comparisons to CCM:

  • Increased material strength, thermal conductivity, and coefficient of friction
  • Reduced temperatures
  • Significant increase in disc life, especially under track conditions
  • Density similar to CCM, but potential for reduced weight due to ability to reduce disc and pad dimensions
  • Wear extent can be determined by visual inspection

CCM-R discs and pads are delivered pre-bedded with a specific friction material for street and track use which will operate in a wide temperature range. If the customer is using the vehicle for primarily track or race use, a race-only material can be specified.

  • Production Process Time: Approximately 28 weeks (7 months) for production from start to finish.

Pre-Bedding:

Pre-bedding is the process of transferring pad material to the disc surface in a controlled environment. It is critical to have a transfer layer of pad material on the CCM-R disc to generate friction. Due to the material strength of CCM-R and the high level of surface hardness, it takes considerable pressure and temperature to transfer pad material onto the disc surface. This is done on a high inertia brake dynamometer using very specific computer controlled programs at the Brembo factory.

Brake Fluid – Brembo Racing

Upgrading brake fluid for spirited, track or racing use is easily one of the most overlooked things when thinking of upgrading any component or part of the brake system.

Brake fluid performs a very critical function as it is the “life blood” of the brake system, as it is the foundation to hydraulically transfer brake pedal effort to the brake caliper’s pistons. Brake fluid also performs a vital function of lubricating caliper piston seals Brake fluid performance (or the lack of) can directly affect brake pedal feel, pressure and consistency through the operating temperature range. It is also one the most cost effective ways to improve brake pedal consistency (avoiding spongy pedal) under high temperature use.

Dry Boiling Point – Top professional racing teams purchase brake fluid based on several variables that include but are not limited to: dry boiling point, compressibility, viscosity, pedal feel, consistency, and its ability to recover after boiling. While dry boiling point is important, a lot of performance gain can be had from a fluid which has strengths in a lower fluid compressibility.

Most of the dry boiling points* of the top racing brake fluids sold to professional motorsport teams are rated very high so to have substantial gains in fluid performance, other factors can be the focus of development.

 * NOTE: The only way to verify the exact boiling point of a brake fluid is to test it in a fluid lab as there is no industry wide standardized testing for fluid. To properly compare fluids and have accurate results: the test has to be done at the same lab, with exactly the same environment and conditions.

Compressibility/Viscosity – A brake fluid with low compressibility offers a more positive pedal feel which is more consistent during brake applications.

Recovery – The fluid’s ability to recover to its most optimal performance after boiling is a crucial factor in brake fluid performance.

Street Use – Most professional racing fluids are not suitable and/or approved for street. The Brembo LCF600+ is DOT approved and is suitable for street and track use.

Brembo Racing brake fluids are proven motorsport brake fluids with low compressibility, high boiling points, even under the highest temperatures and demanding conditions.

HCF (HYBRID CARBON FRAME)

HCF is a construction of additional structural carbon which shape strengthens and stiffens the shell. The new result is a hybrid shell, part in carbon and part in fiberglass, particularly performance and safe, that represents a true new seats generation for technique, performance and market.

– The back carbon reinforcement (HCF) stiffens the entire shell improving resistance in case of side impact
– The shape of carbon structure has been designed to strengthen the areas subject to higher loads
– Reinforcing the most stressed areas had allowed composing a plybook that enlightens the remaining areas, with consequent weight saving on the total shell.

DOUBLE HARNESSES SLOT

Provides adjustment of the height of the harness making the seat absorb part of energy in case of impact.

Proper belt placement insures the seat edge is utilized during a crash rather than drivers shoulders. With this target we doubled the shoulder belt adjusting slots to better adjustment for various driver heights. In this way, in case of impact, the vertical force will be supported by the seat improving safety of the driver.

COOLING VENTILATION HOLES INTEGRATED IN BACKREST

External temperature and driving conditions of the driver are one of the critical areas in which FIA is working to improve safety of crews.

The back, in the lumbar area in contact with the seat is even more complex. It is thanks to ergonomic studies made for OEM that we tested a solution that includes seatback holes allowing for hot air exchange to improve driver and co-driver cooling.

Starting price = $1,222.00

Brembo Racing RB340

One of the top teams participating in the FIA WEC series is Larbre Competition, one of the only teams in the world racing with the Corvette platform as a non factory effort in the top level of professional motorsport. For 2015, Larbre Competition is racing a C7.R in the FIA WEC series.

The FIA World Endurance Championship (WEC) is starting to become the leading series by many car manufacturers and their technical partners to showcase new technologies in the LMP (Le Man Prototype) & GT (Grand Touring) Classes. The FIA WEC features endurance races (6 hour races and the 24 hours of Le Mans) and is a global series racing at challenging circuits in the United States, Europe, Asia and the Middle East. Stiff competition between factory run and private customer teams in all the various classes means teams choose to work with only the best technical partners to have the most competitive advantage.

Larbre Competition won class honors with a Corvette C6.R at the 24 hours of Le-Mans in 2012 using Brembo Racing RB340 brake pads. Larbre Competition also finished the 2012 Le Mans 24 hour race without changing brake pads or loss of performance through the race.

Brembo’s RB340 material is unique in construction and the optimal performance is dictated by the energy of the brake system, not so much the disc or pad direct running temperature. This means the material offers excellent wear resistance, high initial bite, stable friction levels (the performance does not degrade as much at elevated temperatures) and good modulation in a wide range of conditions. The combination of wear resistance and high initial attack means the driver does not need to push the brake pedal as hard to achieve the same stopping power. This is easier on the driver and means a common material can be potentially used for long and short races.

Brake pads and fluid are two very small things that make a huge difference that most people overlook. Pads and fluid help fine tune brake system characteristics like initial response, fade resistance, and pedal consistency. For an endurance race such as a 24 hour race, one of the many critical factors is the wear resistance of friction materials to avoid doing brake pad or rotor changes as this can cost valuable time in the pits. If changing pads or brake discs can be avoided altogether, this is the most ideal scenario.
