Product details
This black Powerlite is the wider-rotor configuration with four 1.00-inch stainless pistons. A forged radial body positions the top-retained pads around a rotor 0.79–0.86 inch thick. Its compact dimensions are useful in space-limited assemblies, provided the bracket and wheel clearances are checked for the actual installation. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Measure the rotor and compare the 5.08-inch mounting pattern with the current brake package. Check the full caliper outline against the wheel and hub, including the hydraulic fitting. The 1.58-square-inch piston area must suit the intended master cylinder and brake balance, and the correct pad shape must be retained.
