Product details
This right-hand GT rotor provides the narrower 1.10-inch friction section within the 14-inch Spec-37 range. Its plain-finish casting uses 72 curved vanes and a slotted face, with twelve holes attaching it to the 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.
