FNSL4R rear race kits provide high capacity braking for dedicated track use on Corvettes and other purpose built vehicles equipped with 1988-1996 C4 Corvette rear suspension. The parking brake is eliminated and the original equipment single piston combination caliper is replaced with a high efficiency, forged aluminum, fixed radial mount narrow four piston Superlite caliper. The forged caliper bodies feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores and high resistance to abrasion and corrosion throughout. Stainless steel pistons with internal damping springs are used with controlled retraction, high temperature seals for long term durability and consistent performance during extreme duty use. The caliper piston volume is fully compatible and matched to the output of the OE master cylinder on production based Corvettes, and easily configured with balance bar manual brake pedals in non-OE based purpose built race vehicles. The calipers are coupled with weight-saving two-piece rotor assemblies using 12.88” diameter Spec37 alloy direction vane GT series rotors mounted to the OE hubs with forged aluminum hats. High-temperature, high friction, endurance race compound brakes pads are specifically selected per application to provide high brake torque with smooth driver control and long wear in sustained high temperature competition.

Fitment Notes

1. Road Race kits contain high temperature racing pads. Extended low temperature use will cause premature rotor and pad wear.
2. Production chassis Corvettes require flexline kit 220-8177 for installation.
3. Custom built vehicles using adapted 1988-1996 Corvette suspension must specify the required line length.

About Wilwood Engineering

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.
