Cobalt XR1 is an extremely high torque material with a rapid, yet controlled, transition from an aggressive initial bite to a 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 has unmatched disc life and finish versus any other competing friction material of comparable torque.
The XR1 compound effectively bridges the gap between "sprint" and "endurance" materials, providing an optimal balance of ultimate high torque and very good wear rates. Equally 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.
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

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.
² As compared to any competing material with torque levels within ±10%
