Wilwood Billet Superlite 6 Front Kit for 1993–1997 Chevrolet Camaro / Pontiac Firebird — 12.88-inch GT Slotted, Black

The six-piston Billet Superlite package brings a 12.88-inch Spec-37 rotor to the 1993–1997 F-body front end. This Billet Superlite six-piston front brake kit combines black powder-coated 6-piston calipers and 12.88-inch GT-slotted rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake system.

Fitment & Compatibility

This front package is for the listed 1993–1997 Chevrolet Camaro and Pontiac Firebird applications. Its six-piston calipers are machined from billet aluminum, while the 12.88 x 1.10-inch vented rotors use Spec-37 iron. Those dimensions determine a different wheel envelope from the factory brakes. Use DS406 to compare the back of the wheel spokes and the barrel with the complete caliper/rotor profile; a nominal 17-inch wheel is only the starting size guide. The kit mounts through the specified front hub and spindle arrangement rather than supplying replacement hubs. Check their condition and the installation drawing before assembly. Hydraulic flexlines are a separate purchase, with Wilwood identifying the F-body line kit in the manufacturer references.

The application table below identifies the model-year and factory-equipment combinations. Match the entire row, including its numbered notes.
