D8-4 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. D8-4 calipers mount in the stock location over stock rotors, use the original style D8 brake pads, and fit snugly inside most ’67 or newer production wheels. Some wheels, including the 1965-66 OE “JK” code steel wheels and a few aftermarket replica alloy wheels, will require a 3/16” or wider wheel spacer for clearance. Kits contain DOT compliant stainless braided brake lines and high friction Promatrix brake pads.
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 250 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
