OPTIMIZED ONE PIECE UNIT
COBALT XR1
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.
COBALT XR2
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.
COBALT XR3
Versatile, medium-high torque material with a solid initial bite and a slightly rising torque curve. Unsurpassed cold performance, torque stability, consistency and modulation/release for this level of friction make the XR3 an ideal compound for Club Racing and Track Day/HPDE customers, particular in moderate to lower inertia vehicles. Also recommended for rear-axle use on vehicles over 2800lbs, delivering optimal straight-line braking performance, stability and controlled rotation while trail braking.
