The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility
Match this component to the documented Custom twelve-bolt brake systems. Confirm the mounting stack, center location and rotor hardware; vehicle model alone does not establish compatibility with a modified brake system. The blank hub flange is not ready to bolt on. Have a qualified machinist verify the drilling layout, register and finished mounting surfaces for the intended assembly.
