Product details
Left-hand cooling vanes distinguish this 12.72-inch GT rotor from its opposite-side companion. The heavy-wall Spec-37 ring mounts through eight 0.316-inch holes, with a 6.53-inch registration bore that must suit the intended hat. Disc brake systems have been Wilwood’s focus since Bill Wood founded the company in 1977. Based in Camarillo, California, Wilwood designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. The rotor is one part of that system and needs compatible pads, calipers and mounting components.
