Wilwood Front Superlite 4R/ST Road-Race Kit for Camaro/Firebird, 13.06-Inch Rotors and Thermlock Pistons — Selected 1993–2002 Applications

This dedicated F-body road-race package combines four-piston Superlite 4R/ST calipers with 13.06-inch GT rotors. Earlier listed Camaros require the specified 1998–2002 spindle conversion rather than a fit based on the original model year alone. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.

Fitment & Compatibility

DS-1088 requires the 1998–2002 F-body production spindle originally used with twin-piston front calipers; earlier listed Camaros require that spindle conversion. BP-35 pads are for high-temperature road racing and wear prematurely in extended low-temperature use. The catalog hat patterns conflict with DS-1088's 5 x 4.50/4.75-inch hat description; have Wilwood confirm the actual pattern. Included hose kit 220-6746 and the 17-inch wheel template must also match the installation.

Listed models: Camaro; Firebird. Use the fitment table below for the individual years, submodels and equipment conditions.
