Product details
The twelve-lug mounting center makes this GT rotor a specific choice for a snap-ring retained system. It pairs a 13-inch Spec-37 friction ring with right-hand curved vanes and is supplied without factory burnishing. 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.
