Description
Discontinued please see our Wilwood Powerlite kit – https://v8roadsters.com/product/4-piston-rear-upgrade-kit/
For the rear axle application, we’ve worked directly with StopTech and engineered the lightweight STR-21 caliper over both the sport and non-sport rotor. The STR21 was designed to be used for the rear axle that requires less pad volume than the STR-22 and non-vented, solid rotors. This package can be implemented in smaller wheel diameters, typical of most front-wheel drive race cars. Even with its smaller size, the STR-21 maintains caliper stiffness and optimal pad wear to provide the best performance in its class. Pad shape for the caliper is D31 which is supported by many pad manufacturers.
