Product details
Black electro-coat differentiates this version of the 13.50-inch GT ring while retaining its straight-vane architecture. The 0.81-inch disc provides a slotted contact surface and the twelve-hole flange used by its matching separate hat. 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.
