Product details
The wide center opening of this HP ring matches the 7.78-inch eight-hole attachment arrangement. Its 12.19-inch outside diameter and 0.81-inch thickness are shared by other rotor families, making the 7.29-inch register essential to identifying the correct version. Wilwood began in 1977 with founder Bill Wood and is based in Camarillo, California, where it designs and manufactures disc brake systems. Calipers and rotors sit alongside master cylinders, valves, fittings and lines in a range serving motorsport, street performance and specialized applications. Selecting these parts together is essential to a correctly matched brake installation.
