Product details

This right-hand GT rotor provides a 13.06-inch slotted friction diameter with a 1.25-inch Spec-37 section. The plain-finish 48-vane ring uses a twelve-hole mounting flange, distinguishing it from the thicker eight-bolt version of a similar diameter. A well-matched brake installation starts with compatible components. Wilwood designs and manufactures disc brake systems that include calipers, rotors, master cylinders, valves, fittings and lines, serving motorsport, street performance and specialized applications. Bill Wood founded the company in 1977 in Camarillo, California; this rotor should be evaluated as part of the complete braking package.
