OFF THE SHOWROOM FLOOR AND STRAIGHT TO THE TRACK: The brand new Cayman GT4 (981) is Porsche’s lightweight platform specifically focused for the racetrack and track day enthusiasts.

THE PORSCHE 911 (991) DNA: Since most of the front end, upright, and suspension components on the Porsche Cayman GT4 are from the Porsche 991 GT3 (911), the Brembo OE (Original Equipment) brakes equipped on the Porsche Cayman GT4 are some of the most sophisticated designed for an OE application.

CAYMAN GT4 VS. 911 GT3: The Porsche Cayman GT4 Brembo OE brakes utilize 6-piston aluminum fixed monobloc calipers front and 4-piston aluminum fixed monobloc calipers in the rear. The Cayman GT4 uses heavy duty 380 x 34 mm ventilated front & 380 x 30 mm rear brake discs similar to what is equipped on a Porsche 991 GT3. The Porsche Cayman GT4 brakes also uses a wide annulus (radial depth) front and rear pad for maximum swept area, heat dissipation, and pad life. The OE pads are also 18 mm thick front and rear which is comparable to most high performance aftermarket calipers.

HOW THEY DIFFER FROM EACH OTHER: While the Porsche Cayman GT4 and 991 GT3 are similar on paper in many ways, there are some of major technical differences between the Porsche 991 GT3 and Cayman 981 GT4.

These technical differences significantly affect overall brake balance setup and performance.

  • The Porsche Cayman’s suspension setup (especially the rear), geometry, and dynamic weight distribution is fundamentally different resulting in an overall chassis balance that is more sensitive to braking inputs than a GT3.

The Cayman’s inherent tendency to pitch more under braking increases front axle brake demand, but inherently results in unsettling the rear axle under braking. However, this can be tuned with managing the operating temperature of the brake disc and also by using different friction compounds that are optimized for the specific brake temperature windows.

MID-ENGINE VS. REAR-ENGINE: A mid-engine platform will generally demand less out of the rear brakes compared to a rear-engine platform with all the weight sitting on the rear axle. The Cayman’s mid-engine design also inherently results in the rear axle getting unsettled easier under braking inputs.

STABLE DISC TEMPERATURES: The rear Brembo 380 x 30 Type 3 racing disc, used for the GT4 application is offered in a 48 vane configuration. This 48 vane disc configuration stores more heat in the disc, which allows for more stable rear brake temperatures, resulting in improved disc life for the intended use.

  • The Porsche Cayman GT4 generally weighs 200 lbs less than a 991 GT3 (Cayman GT4 Curb Weight – 2955 lbs, 991 GT3 Curb Weight – 3150 lbs).

Overall weight and weight balance directly influence a vehicle’s brake demand. The Cayman GT4 with less overall weight (especially over the rear axle) will also demand significantly less out of the rear brakes compared to a 991 GT3.

  • The Porsche Cayman GT4’s bumper design and aerodynamics are different and more adjustable than a 991 GT3. The Cayman GT4 features an adjustable front diffuser and rear wing to increase downforce and grip versus the non-adjustable parts on the 991 GT3.

The Porsche Cayman GT4 has an adjustable Rear wing to add rear downforce.

Bumper design has a significant influence on airflow to the brake system which results in different braking demands on the front and rear axles. Increased downforce and grip also affects brake balance and demand depending on the exact chassis setup.

IN CONCLUSION: 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 discs are directionally ventilated for enhanced cooling and slotted for better performance and continuously refreshing the pad surface. Brembo Performance 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.

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.

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”.

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

PORSCHE 911 GT3 & TURBO (997): BREMBO 2-PIECE TYPE III 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.

“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.”

Andrew Davis, 2011 Grand-Am Rolex GT champion with Brumos Racing.
