Forged Superlite 4R Big Brake Front Brake Kit (Race)

This kit is configured for dedicated road racing on all 1982-92 Camaros and Firebirds using the OE factory single piston caliper spindles that have been modified to accept the Wilwood caliper brackets. 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 GT competition series 12.19” 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 using forged aluminum hubs and rotor mounting hats for assembly onto the spindles. Mounting brackets, including all premium grade fasteners, secure the calipers in the stock location, after the required spindle modifications have been completed. A detailed illustration of the required modifications can be found on page 2 of the assembly instructions. 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.
