RacingBrake is pleased to team up with Cobalt Friction - Performance industry's best friction manufacturer on all our caliper kits, which are also used in OE calipers on most popular motorsports cars.

All Cobalt Friction XR-Series Racing Brake Pads feature true 100% "no-bedding required" to achieve full frictional performance, unlike most traditional race pads which require very specific bedding instructions for proper function. Unmatched friction vs. temperature stability and consistency.

Additionally, Cobalt Friction materials exhibit unmatched disc finish and life as compared to any competing racing friction. Cobalt XR1 is an extremely high torque material with an aggressive initial bite and medium-high, linear rising torque curve. Excellent friction stability and consistency coupled with very good modulation, threshold control and release characteristics over the industry's broadest operating temperature range.

The XR1 material is chosen by us for its unmatched disc life and finish versus any other competing friction material of comparable torque. Well-suited for a wide range of platforms, including those with active aerodynamic profiles as well as limited downforce applications, and/or ABS-equipped as well as non-ABS vehicles, due to the direct line pressure to generated torque relationship.


RacingBrake's XR70 compound is also a good choice for track racing:

I have been testing the new RB Brake setup. I was able to get the new XR-70's pads for both my front and rear setup. I also purchased the RB Brake rotors as well for my racing setup. Last year I ran the Endless ME-20's with the Alcons/AP J-Hooks and then the RB Brake rotors. I just finished a two day session at Dayonta (5) session a day for 30 minutes each day. That's a total of 5 hours of racing. I ran the XR-70s and have 90% left of pad. I measured them prior to putting them on, so when I am done with Robling this weekend I will post the different thickness once I get back. I like the setup so far working together with the RB Rotors and Pads. I do not have any fade in the pads and total confidence in the setup. No shakes or vibrations.

Like I said, I am going to a smaller track and I want to get these things heated up pretty hot and see how they do. Daytona is great for 190 mph and coming down to 100 in the bus stop, but you have a ton of road to cool them down. I like the RB design because of the open slot. I know we are all different and have our likes, however after running two years on ME-20's I am liking the XR-70's. The ME's kept eating my rotors. The XR's squeak just like the ME-20s.

This year I am going with the complete RB setup for the One Lap of America event. I will also post before and after pictures once done.
