This kit is configured for dedicated road racing on all 1998-2002 Camaros and Firebirds, and any 1993-97 models that have been upgraded with 1998-02 spindles racing in categories that do not allow slotted face rotors. The four piston FSL4R/ST calipers used in this kit feature a forged aluminum body with a Type III Mil-Spec hard anodized, medium gray color finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. Thermlock® pistons are used to reduce heat transfer from the pads to increase fade resistance, and to extend service life by decreasing temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish. Caliper piston volumes are matched for full compatibility with the OE power brake booster and master cylinder, and are easily configured with manual brake conversions and balance bar pedals using appropriately sized master cylinders. Spec37 alloy HD competition series 13.06” diameter directional vane rotors provide high cooling efficiency with rugged durability and thermal stability in sustained high heat competition. Unsprung and rotating weight are minimized with forged aluminum hats for mounting the rotors to the OE hubs. Mounting brackets, including all premium grade fasteners, secure the calipers to the spindles in the stock location, without the need for modifications. This championship proven system is completed with high temperature, high friction, endurance race compound pads selected specifically by application. Stainless steel braided flexlines are included in each kit to complete the installation.
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.
