Cobalt XR2 is a high torque material featuring an initial bite that is 8-10% lower than XR1, but with the same controlled transition to a linear, rising torque curve. Improved modulation, threshold control and release characteristics make the XR2 particularly well-suited for chassis and tire combinations which do not respond well to excessive initial brake energy, but still require a high average torque level.
Similarly, vehicles normally equipped with XR1 can move directly to the XR2 when low-grip conditions present themselves unexpectedly (e.g. qualifying in the dry, but rain/wet conditions on race day) without sacrificing or experiencing a change in pedal feel, consistency, or brake capacity.
As with all Cobalt Friction XR-Series Carbon-Ceramic friction materials, the XR1 does not require any bedding¹, and will deliver 100% consistent performance within 1-2 laps, while still maintaining a superior, uniform disc finish.
Cobalt XR-Series Features:
No Bedding Required to Achieve Full Frictional Performance¹
Unmatched Disc Finish with a Minimum 50% Improvement in Disc Life²
Highest Torque vs. Initial Disc Temperature Stability and Consistency
Highest Repeatability vs. Number of Heat Cycles of any Racing Brake Pad

¹ Full torque potential of all Cobalt materials will be realized within 1-2 laps. However, proper on-vehicle or inertia-dyno bedding will yield an 8-10% improvement in wear rates.
