Product details
Threaded 5/16-24 mounting points distinguish this right GT rotor from the smaller-circle through-hole version. The 12.19 x 0.81-inch ring requires a hat designed for its 7.62-inch attachment and 7.13-inch register. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility
Installation requires a hat or hub designed for the 7.13-inch rotor register and 8 x 7.62-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 0.81-inch width. The ring alone does not define a direct-fit vehicle or axle application. Select pads and operating duty to suit the rotor material and the intended brake system.
