Wilwood Chevrolet Corvette Right Front D8-6 Caliper (1965–1982), Six Pistons / Type III

The anodized D8-6 replaces the right front caliper on a stock-layout 1965–1982 Chevrolet Corvette. Six differential stainless pistons use 1.88/1.38/1.25-inch bore groups with the original D8 pad format. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. The company makes and designs disc brake components and systems for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
