[More Info]

Forged Narrow Superlite 4R-QS caliper rear road race kits provide matched performance in conjunction with FSL6R and AERO6 front race kits on vehicles built specifically for competition. FNSL4R-QS calipers use high temperature, fluid resistant high gloss “Quick-Silver” finish, stainless steel pistons to retard heat transfer from the pads and high temperature seals for reliability in sustained high heat. Radial mount brackets attach the caliper in the stock location. GT series directional vane competition rotors provide high efficiency cooling and mount to the drive axles with forged aluminum hats. Kits also include high temperature, high friction race compound pads and all premium grade fasteners.

Fitment Notes

1. Road Race kits contain high temperature racing pads. Extended low temperature use will cause premature rotor and pad wear.
2. Kit may fit some 18" wheels. Check wheel clearance diagram in kit installation instructions before purchase.

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.
