The wilwood powerlite 2r/st is a radial-mount caliper designed to be a direct bolt-on for late model van diemen and citation ff2000 cars. The billet aluminum body is nickel plated for heat resistance, with stainless steel bridge plates and internal fluid passages (no vulnerable crossover tubes).
The thermalock insulated pistons keep heat away from the brake fluid, and internal piston damping springs offer consistent brake performance, corner after corner.
Each caliper weighs just 3.44 pounds empty.
Accommodates brake rotors from 1/4" to 1/2" thick. 10x1.0mm female inlet port (adapter fittings available separately). Two-piston caliper (1.75 inch pistons) is legal for scca ff and fc.
