Here is the best run I had at Buttonwillow 13 CW with a 1:55 this last weekend in the Time Trial portion with NASA SoCal which would have got me third place but the track timing was not working so it got pushed to the previous time of a 1:56. My previous best was a 2:04. I changed to the RacingBrake USA 2 piece forged calipers and sintered metallic pads which gave me substantial braking capability as well as Pirelli Pzero slicks and there was a substantial difference over the Toyo R888 which I ran all of last year. Big props to Stephen Fuller for introducing me to JB Racing Tires for the used slicks. I know that I have at least 3-4 seconds as a driver and the next upgrade needs to be a proper suspension which would probably be at least another 2-3 seconds because the car is still soft and squishy and needs an aggressive coil over setup. I am also still classed low so I can either bump power or reduce more weight. Enjoy.

So after the first run with the new calipers I want to give a debrief on the Racing Brake Calipers and pads. I ran the Brembo system for an entire year and was satisfied overall. The Racing Brake 2 piece forged calipers provided more braking power and doing so more consistently over the OEM system. When braking it feels as if there is a 50% increase in braking power bite and ability as well as a smoother transition.
The other component of note is the sintered metallic pads and the use of them on the Carbon Ceramic Rotors. I ran the CCR for an entire season and now have switched to the Racing Brake Sintered Pads and have seen their claim of the sintered pad adding a layer to the CCR as well as healing the fractures caused by the OEM pad. I ran the car for 6+ hours at the last event at Buttonwillow 13CW in both Time Trial and Race Group sessions ranging from 20-35 mins each over 2 days. The brakes responded flawlessly every session. There were no instances of brake fade and the brakes had very aggressive bite. I have a little over a millimeter left on the pads on all 4 corners. I consider braking still one of the areas of most improvement as a racer and for faster lap times however my previous best time was a 2:04 and I was able to trim that down to a 1:55. |

So we have been experimenting with brake pads and settled in on our winner for the Z/28.
" As the G Lock pads kept wearing and becoming more "intimate" with the rotor, they were much better. Front stretch braking between the 3&4 was too soon but I'm pretty conservative. I could have easily started at the 3 marker and had room to spare. After almost 300 miles and a string of 2:11s, I finally put together a 2:10.5 with a virtual best of 2:09.4. I will be in touch soon about the alignment." Stephen F. These pads appear to be easier on the rotorZ as well. All our pads are ordered pre-burnished to reduce the bedding required.

Come see how the Racing Brake Calipers and Sintered pads do at Fontana Auto Club Speedway May 20-21 for our race with NASA.

We just had Russ's brake checked yesterday, everything looks good with normal pad wear.
I (Warren) will be at Auto Club Speedway, Fontana, CA Sunday (5/21) afternoon from 1:30 to 4:00 pm with some parts sample. If you happen to be there and like to find out more about this brake set up please stop by. Thank you. Last edited by RacingBrake; 05-19-2017 at 05:24 PM. |

RB CCM brake kit installed on a 991 TurboS (18" wheels). Calipers are equipped with sintered track pads.

Sorry for the delay. We finished out the season and took second place for the NASA super Touring Series overall and third place at the western nationals. The Racing brakes have been phenomenal. The sintered metallic pads have lasted 2-3x longer than OEM Brembo pads and also added life to the Carbon Rotors. I highly recommend the set up.

You can buy a pair of GM factory rotors for 2883.00 a little over half of what there asking. They would only be cost effective if they lasted twice as long.
