Wilwood Black Superlite Front Disc Assembly with Drilled 13.06-Inch Rotors, Listed C10 Wilwood Aluminum Pro Drop Spindles Only

Black Superlite calipers use BP-10 pads against drilled-and-slotted Spec-37 rotor rings in this C10 front assembly. Aluminum hats and brake-side brackets are supplied for the specified Wilwood Pro Drop suspension, rather than as an OE-spindle conversion. Wilwood Engineering has designed and manufactured disc brake systems and components since its founding by Bill Wood in 1977. The company is based in Camarillo, California, and serves motorsport, street-performance and specialized applications. Its calipers, rotors, hydraulic master cylinders, valves, fittings and brake lines need to be matched to the complete system in which they operate.
