Wilwood Rear Black 12.88-Inch Drilled/Slotted Kit, Corvette C2/C3 (1965–1982), Original Parking System

Black Superlite 4R calipers and drilled/slotted rotors form this Wilwood Corvette rear conversion. The 12.88-inch friction rings are carried on separate hats that accommodate the existing internal parking-brake shoes. This selected SRP package specifies BP-10 pads, unlike the GT rotor variant's BP-20 specification. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Inspect the Corvette's original hub, parking-shoe mechanism and axle-stud pattern before installation. The kit replaces the service-brake components and rotor hats, rather than providing a new complete parking assembly. Follow DS624 for bracket shims and suspension clearance, including the end-link bolt where required. Provide compatible hydraulic lines and verify the wheel template at the spokes and inner barrel.

Match the individual model, year, submodel and brake configuration in the fitment table below.
