Wilwood D8-4 Front Caliper Kit Clear Corvette C2 / C3 65-82D8 4 Front calipers are a direct bolt on replacements for the OE calipers on all 1965 82 Corvettes. Type III hard anodized forged billet aluminum bodies, stainless steel pistons, and high temperature seals put an end to the rust, bore pitting and seal failures that plague the OE caliper design. D8 6 calipers provide low maintenance performance, a huge weight savings, high temperature reliability, and the added benefit of six piston pad clamping power.
