Before we get into more discussion on other design aspects, can any of you share with us about our brake experience and where the improvement is needed.

Over the past 10 years due to the increasing popularity of turbo charging and/or horsepower, most motor companies simply equip with larger brakes (bigger and thicker rotors) and naturally they become heavier and heavier. Just take a look from our track of the trend:
http://www.racingbrake.com/v/main/oe...it_compare.asp

The heaviest rotor we have ever dealt with so far is Mercedes' C63, 360x36mm weighs 36 lbs. Using larger rotor is no exception to Porsche, I am sure Panamera's 390mm rotor will surpass C63.

Eric called me for his 993 (1996), the stock front is 308 (12") x32, but look what's the late models (997) today 350 (14"), 380mm (15") is not uncommon. The other trend I see is that the brake pad is growing substantially - longer and taller. For example 993 uses 50mm height pad and now 65mm is normal.

Bigger and heavier sound the right way to deal with the increased speed and horsepower but are they really better? Do you think the brake is overgrown more than necessary?

I run 350mm rotors on all 4 corners of my 996 turbo, with the 6 piston front calipers and 4 piston rears. The front brake pads are huge. I know it is all unsprung weight but for the track it works. I have never had brake fade nor a spongy pedal. I do use SRF brake fluid. Whether it's too big I can't say from an engineering perspective. I know it is very effective stopping my car which weighs about 3500lbs.

How much do your rotors weigh in a 350mm size?

"Efficiency" is what the performance business is all about, with the same output can we reduce the input, or for the same input can we maximize the output.

So if we are looking for a more efficient brake set up, "fade fee" is only a minimum criteria. I think an efficient brake system should be:

Lighter rotational weight that can provide quick pedal response in acceleration and deceleration.
Good in modulation so the driver can have a predictable control over various driving conditions.
Able to deliver Strong yet Consistent brake torque under extreme high heat / stress, so the pedal efforts can be minimized, and more importantly to increase the drivers' confidence to go faster and brake deeper.

Assuming all aftermarket performance brake supplies/upgrade can equally meet the above, then the next to consider is which brand would last longer, and if they all last about the same, whose cost (initial purchase & replacement) is lower...

Our average weight for a 14" (355mm) rotor is about 17-19 lbs varied by the brake pad height.

Default Complete RB CCM Brake Kit for 991 GT3

RacingBrake is pleased to present this CCM brake package with the following feature:

Package# RCCB-POR-01

CCM Discs: Made by Brembo and supplied by GM for the CCM brakes as the latest Corvette C7 ZR1 & Camaro Z28

Front: 394x36mm
Rear: 390x32mm

Calipers: Designed and made by RacingBrake

Front: 6 pistons (Track duty)
Rear: 4 pistons (Track duty)

Brake Pads: Same as ZR1/Z28 (for CCM application):

Front: D1395
Rear: D1165
Three levels of compound available: RB XT910 for performance street, OE ZR1 pad for street and medium tracking, RB sintered pads for dedicated tracking.
Rotor Hats and Hardware:

Exclusively designed and tooled by RB for CCM rotor assembly to assure the rotor integrity with consistent brake torque delivery under extreme braking conditions, easy to assemble/disassemble.

Benefit of RB CCM Kit.
  • Affordable pricing to own.
  • Help you make a quick decision when ordering your GT3 - Just tell dealer thanks but "No pccb"
  • Transform your standard brake or existing pccb to the latest CCM set up as Corvette ZR1 and Camaro S28 for the flexibility of disc and pad swap.
  • Low replacement cost on consumables (discs and pads), you can just purchase from GM dealers or online stores (Amazon or eBay) direct for cheaper price with more compound choice from other aftermarket.
  • Kit is built for DIY installation - Including SS brake exclusively developed by RB that eliminates OE rigid lines, brake pads also come with wear sensor connector.
  • Easy on going maintenance - RB's open top calipers allow you to change the pad w/o having to detach the caliper. Brake fluid change and bleeding will also save you frustration on our flexible lines.
  • Receive professional advice and service from RB*, before and after your purchase including our stock on CCM discs and pads for emergency replacement.
*We have been building similar CCM brake kits for GT-R, Mercedes GT-S, Camaro ZL1, Corvette ZR1 (Upgrade light weight hats) and Audi R8/RS5 etc. Under development are Porsche's, Ferrari F430 Scud. and Viper G5.

It takes about 10 months all together to complete this development, the proto type fitment was confirmed earlier with production release in different stages.

Most of the components are already on shelf, so we are only a few weeks away before shipping the kit.

Pricing and web listing will be updated within a week or so, in the meantime please review this offer and fee free to address your question or concern.

Thank you.
