Icarus posted this in his thread, but thought it a good idea to make its own.

its a massive kit, not quite a race caliper, wonder how it compares to the stock, or its used just because it can accommodate the larger rotor?

here is what a real race radi-cal caliper looks like

Nonstandard pad. This kit will live in the Alcon stratosphere. Good kit I'm sure, but too expensive.

I'll put my Racing Brake ones against them anyday.

AP UK uses Ferodo a lot, always can use the supplied pads for street and order special made from endless in your compound of choice.

just finished 2 days at INDIE. Ran 8x20 min and 3x15 mint sessions. Only two cars had faster times, and open wheel racegroup car was 2-3 seconds faster and a modified ACR with full slicks only running 2 hot laps per session for  TT was a few 10ths faster and he was overheating. No fade no problems. Was 2 seconds faster than my previous best but likely due in part to the new DSC controller and tractive RTx suspension which I will review on the DSC thread. Bob at BSE Performance inspected the brake and said you would be hard pressed to even say the brake or pads had even been used.

By the way temps ran into the low 90's over the weekend. Also I was able to brake later into the high speed corners. Prior to the AP bakes I had oem calipers and PFC 08 pads which are phenomenal pads,ungodly expensive but I'd wager better than the ones you are currently running by a long shot. I went through several of the pads and they, without exception wore completely flat. My guess is the AP pads will be just as good and less expensive.

Just to be clear, there are two different AP Racing kits. One is more street oriented:

 

Front

https://www.apracing...p8521z1000.aspx

 

Rear

https://www.apracing...p8540z1000.aspx

 

 

And the other on is a race/track kit by Essex Parts which I believe drk is running. This kit also uses more traditional/common pads:

 

Front

I believe they are also working on a rear kit.

$5500 is very comparable to a full RB CCB brake kit.

 

Some advantage of CCB kit over conventional iron kit:

  • Bullet proof performance and lasting durability proven by track only in a Mustang GT350R (w/sintered pads), and Porsche 991 Turbo and Cup car for professional racing.
  • Brake disc is a same as ZR1/Z28 front easy to source (online or GM dealers) at low cost (swap the disc and re-use RB hats).
  • Brake pad is a standard FMSI configuration (Swap with OE GTR pad D1382 or upsize to ZR1 pad D1395) for multiple choice of compounds and suppliers at low cost.
  • Even calipers are swap-able between RB's and GTR, RB calipers are made from forged aluminum alloy and is a direct mount to OE upright w/o needing any spacer.

You have full control after you purchase RB CCB kit for future maintenance and replacement w/o having to contact us but of course we are available if you ever need it. If you think hard on the 100% interchangeability of RB CCM to OE iron, you know you will have a complete "back up" set of components with you in case something happened it's always can be under your own management w/o panic - A distinct feature only available from RacingBrake no one else can.

 

Should you still consider and settle with these conventional iron kits and worry about the wear and tear or fading etc. while CCM brakes has been made so affordable and reliable these days.
