Wilwood Rear Superlite 4R/MC4 Brake and Parking-Caliper Kit for Chevrolet Corvette C4 (1988–1996), Black with 12.88-Inch GT Rotors

Black Superlite 4R calipers provide hydraulic service braking, while separate MC4 mechanical calipers provide parking operation on this C4 rear conversion. The 12.88-inch rotor rings mount through aluminum hats to the retained Corvette hubs. The manufacturer, Wilwood Engineering, was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc systems and component parts across motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and lines. Those individual parts must be selected in the context of the complete brake system.

Fitment & Compatibility

Match the documented 1988–1996 C4 rear suspension. Production Corvettes need separate parking cable kit 330-14891 and rear flexlines 220-8177. A custom chassis using adapted C4 suspension instead needs the appropriate universal cable arrangement and a measured hose length.

Models represented in the detailed applications: Corvette. Each is subject to its individual year, trim and brake/suspension condition. Use the fitment table below to confirm year, model, trim and brake or suspension options.

For a fitment check, give PMB Performance the vehicle details and the actual brake and suspension hardware. Our team has over 20 years of experience working through parts compatibility.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
