Wilwood Superlite 6R Front Brake Kit for C10 Wilwood Modular Pro Drop Spindles, Black Calipers and 12.19-Inch GT Rotors, Hubs Separate

Black Superlite 6R calipers and 12.19-inch iron GT rotor assemblies form the brake portion of this C10 Pro Drop installation. Aluminum hats, BP-10 pads and caliper mounting hardware are supplied; the required hub/spindle assembly belongs to the separately purchased ProSpindle kit. Founded in 1977 by Bill Wood, Wilwood Engineering is now based in Camarillo, California, where its work centers on disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized installations; selecting these parts requires considering the complete braking system.
