Interview with Jon Sibal

  1. It seems as though I’ve seen you everywhere, but I am still not too familiar with your background. If you can, can you let us know a little about yourself?

    I’m just an average guy who finds art as a great way to express myself. I’m an Automotive Artist where I design body kits, liveries, concept and speculative renderings, etc. I’m also a Comic Book artist where I’m an inker for various titles from Image, Marvel, and DC Comics. I’ve always loved cars and been in the local So. Cal import scene since the early 90’s.

  2. So can you tell us about your RWB 964 build?

    I’ve dreamed of owning an RWB ever since it caught my attention way back in the days before they blew up here in the US. While walking at our local Cars&Coffee with RJ de Vera, I told him about a matte black Porsche 964 I saw at SEMA that I thought could be a good donor car for an RWB project. He introduced me to the owner and it turned out that the car went straight to a body shop to have the fender flares redone. We made a deal and a few days later, took delivery of the car. Seeing the car in person for the first time felt like a huge financial mistake because the car needed way more work than I had expected. It sat in my driveway for over a year until I was able to save up enough money to get it prepared and to also afford the RWB conversion. After figuring out a realistic schedule, we thought that it may be a good idea to debut the car in the 2015 SEMA show. Parts started coming which was a directly reflected by my bank account which was quickly being drained. By the time the SEMA doors opened, our project was on display at the H&R booth.

  3. How do you go about rendering your concepts, and are you at all critical of which components you put on the vehicle (form or function?).

    I have some great ideas of what I want the car to be, but when reality hits, some of those ideas gets shut down. So right now, I’m taking it step by step so I can make better decisions on a realistic direction for the car. One thing I know for sure is that I want this car to have the best parts that I can afford which is why we chose Brembo to handle the braking system for it. Along with the Brembo Club Race system, some of the other parts we’ve chosen might be overkill for the car’s current set up, but they’re carefully chosen in preparation and consideration of our future plans for it.IMG_9572_2048px

  4. I was a huge comic book collector, specifically from the 80’s to the late 90’s, so I can really identify with this part of your career. So can you let us know a little more about your time at Image (Awesome?) Comics.

    My first published comic book work was back in 1993 when Image Comics was still in its infancy. I was fortunate enough to be given a chance to learn the craft as I never had any prior experience. I just loved to draw and was hungry to learn. My first published work was under Rob Liefeld’s Extreme Studio as an inker for a monthly book titled “BloodStrike”. Then later on, I got to work with other studios like Marc Silverstri’s Top Cow Studio and Jim Lee’s Homage Studio. It was fun inking titles like Gen 13, Fathom, Tomb Raider etc.Since then, I worked for Marvel and DC Comics and got to work with some great artist and writers on books like X-Men, Avengers, Spiderman, Iron Man, Superman and currently working on a  Batman Earth One Graphic Novel with writer Geoff Johns and penciller Gary Frank.

  5. I know you for your Dodge Challenger which is not only one of my favorite Challengers but also a couple others at RT. That brings me to ask: What other cars have you owned, or would you like to own?
    I’ve owned a Dodge Challenger, a BMW M roadster, and my E36 which were all fun projects to drive and work on. Although all the hard work and sacrifice that went the RWB 964 will probably satisfy my wants and needs for a long while”.

  6. Is there anything you would like to add?

    By God’s amazing grace, the journey to get to reach the goal makes it fun when you have the help and support from family and friends through all the craziness. We’re very fortunate to have the support we received from companies like Race Technologies and Brembo to help make the dream a reality. Special Thanks also goes to H&R Springs, RSTRADA, WORK Wheels, PIRELLI, RJ De Vera, RWB Family, and Team CP.

    Thank you very much Jon for taking the time to do this.

Brembo Club Race Brake System

The Brembo Club Race (XB1E7) brake system offers several racing caliper features such as a hard anodized finish for protection in high heat environments, stainless steel piston inserts for improved heat rejection, 20 mm thick brake pads for extended pad life over the OE (typically a 16.5 mm thick pad), and a swing bridge for easy brake pad changes.

The lightweight 2-piece Brembo disc assembly is a 332 x 32 x 54a, slotted type 1 disc is a substantial upgrade over the heavy inadequate 25+ year old Porsche OE system.

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).

  • OEM INTEGRATION: Brembo 2-piece disc upgrades are designed to work seamlessly with the OE calipers and systems (manufactured by Brembo for Porsche). This guarantees the utmost in safety and seamless fitment.
  • LIGHTWEIGHT: Disc assemblies include an outer iron disc with aluminum bell/hat and provide decreased corner weights to improve vehicle dynamics including handling, acceleration, and braking.
  • TY3 SLOT PATTERN: Extensively used in professional motorsports, the type III slot pattern offers a high initial response with excellent release characteristics.
  • HIGH THERMAL CAPACITY: Greatly improved thermal capacity and heat management over OE discs and other aftermarket discs in the market. This also improves braking performance and allows for greater longevity of the components.
  • FRICTION MATERIALS: Everything we learn by supporting top professional racing teams throughout the world goes into selecting the best brake pad options for all levels of street, track and racing use.

“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 / Sabelt – FIA WEC at Silverstone

The opening round for the 2015 FIA WEC Championship was a very close 6 hour endurance race at Silverstone which saw great results for Brembo brake equipped teams in the factory LMP and GT classes.


  • 1st Place: Audi Sport – Team Joest, Audi R18 E-Tron Quattro
  • 2nd place: Porsche Team, Porsche 919 Hybrid

Both Audi and Porsche LMP1 Prototypes were equipped with Brembo Racing carbon-carbon brakes.

– Brembo’s specific carbon-carbon materials can give the drivers better feedback, control and modulation over other tested materials.

Audi and Porsche LMP1 cars were also equipped with Sabelt harnesses. (Sabelt, a technology leader in safety equipment, is part of the Brembo group).

– Sabelt aluminum adjusters that Audi Sport are using were optimized using FEA (Finite Element Analysis). This process allows for maximum weight reduction without compromising on strength.

LM GTE – Pro

  • 1st Place: AF Corse, Ferrari 458 Italia
  • 2nd Place: Porsche Team Manthey, Porsche 911 RSR
  • 3nd place: AF Corse, Ferrari 458 Italia

The Ferrari 458 Italia GTE and Porsche 911 RSR is equipped with Brembo Racing cast iron brake systems (Calipers & Brake discs).

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 (including 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 classes means the top teams work with only the best technical partners to have the most competitive advantage.
