Corvette C8 Z51 – Cobalt Friction (Rear)

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.
