Product details
Ten mounting holes distinguish this 12.90-inch GT rotor from the eight- and twelve-bolt families. The right-hand Spec-37 ring uses a nominal 1.26-inch section, with 48 curved vanes and slotted friction faces. 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.
