Product details
This right GT ring receives factory burnishing while keeping the narrow 0.81-inch section. Its 36 curved cooling vanes and 11.75-inch diameter support the matching brake arrangement without changing the eight-point hat interface. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California, where it designs and manufactures disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications; each part must suit the complete brake system.

Fitment & Compatibility
The 0.81-inch working width must suit the caliper, while the hat centers the ring on its 6.38-inch register. Check the 8 x 7.00-inch attachment and radial pad coverage before installation. Vehicle make or wheel pattern alone cannot identify a replacement rotor ring. Select pads and operating duty to suit the rotor material and the intended brake system.
