Wilwood AERO6 Front Brake Kit for ProSpindle, Black Six-Piston Calipers, 15-Inch GT Rotors and Aluminum Hubs

For a front end built around Wilwood ProSpindles, this assembly combines black AERO6 calipers, 15-inch slotted rotors and separate aluminum hubs. Its two-piece rotor-and-hat construction and six-piston service calipers are supplied with BP-20 pads for the documented spindle installation. 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.
