Product details
This right-hand GT rotor uses a thick 1.38-inch Spec-37 section within a 13.06-inch outside diameter. The eight-hole 7.00-inch flange is the defining mounting choice, separate from twelve-hole rotors offered in the same general diameter. Founded in 1977, Bill Wood’s Wilwood is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street performance and specialized applications. Its range runs from calipers and rotors to master cylinders, valves, fittings and lines. Choosing a rotor involves matching those surrounding components as well as the vehicle’s intended use.
