Product Description

The Wilwood 140-10789 D8-4 Front Caliper Kit is a direct performance upgrade for the front brakes of 1965 through 1982 Chevrolet Corvette models (both C2 and C3 generations). Designed with Type III hard anodized forged aluminum caliper bodies and stainless steel pistons, this kit offers enhanced durability, reduced weight, and excellent resistance to corrosion compared to the original equipment. The four-piston configuration increases clamping force for improved brake response and fade resistance, making it ideal for spirited street driving and occasional track use.

Installation is straightforward thanks to the bolt-on design that uses original mounting locations and stock rotor fitment. Included ProMatrix high-friction brake pads and DOT-compliant stainless braided brake hoses help deliver improved pedal feel and stopping performance over aging OE components. Note that wheel clearance should be checked before installation - most 15 inch or larger wheels are recommended to ensure proper fitment and avoid interference during suspension travel.
