Wilwood 14-Inch GT Front Brake Conversion, Black Superlite Calipers with Hubs and Lines for Chevrolet Camaro / Pontiac Firebird 1982–1992

A 14-inch GT rotor diameter gives this black F-body kit its specific brake envelope. Six-piston Superlite calipers, aluminum hats/hubs and BP-10 pads are included together with 18-inch front hoses for the documented spindle installation. Wilwood Engineering, established by Bill Wood in 1977 and based today in Camarillo, California, manufactures and designs disc brake systems and their components. The product range covers brake rotors, calipers, valves, master cylinders, brake lines and fittings for motorsport, specialized and street-performance applications. Suitability depends on matching each component to the entire brake system.
