Product details
A scalloped outer edge and drilled face remove material from this 11.75-inch steel racing ring. Its dynamic mounting system allows the specified floating connection, which must be distinguished from a fixed rotor sharing an eight-on-seven-inch nominal interface. 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.
