Product details
This anodized Powerlite uses the 1.25-inch piston option with the 0.79–0.86-inch rotor-width body. Four stainless pistons act in a forged radial housing, with top-mounted retention for the specified pad shape. The caliper should be selected by both hydraulic area and rotor dimensions when servicing a compact brake package. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Verify the rotor’s measured width and centerline before checking the 5.08-inch mounting pattern. The bracket must set the proper radial height and pad contact without wheel or hub interference. Confirm the NPT inlet, available hose space and master-cylinder relationship with the complete brake assembly.
