This dedicated competition road race kit is specially configured for 1998-2002 Camaros and Firebirds, or 1993-97 cars that have been upgraded with 1998-02 spindles in classes where rotor drilling and slotting is prohibited. Four piston, forged aluminum, Superlite 4R/ST radial mount Quick-Silver nickel finish calipers with Thermlock pistons, PolyMatrix H compound race pads, and two-piece 13.06†diameter Spec 37 alloy HD48 directional vane rotors, deliver consistent stopping power and extreme duty durability under sustained high heat with this ready to bolt-on kit. The calipers are volume matched for compatibility with original equipment power brake system output, and easily matched to common master cylinder sizes available for manual balance bar pedals. Kits include braided stainless steel flex lines, radial mount caliper brackets, and all the necessary hardware to complete the installation.
