Product details
Black electrocoat adds corrosion protection to this right-hand GT rotor while retaining the 1.10-inch working width. Its twelve-point attachment and 72 curved vanes identify the 14.25-inch Spec-37 ring used with a separately matched hat. The manufacturer is Wilwood Engineering of Camarillo, California, founded by Bill Wood in 1977. It designs and manufactures disc brake systems, supplying calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Matching this component requires consideration of the complete brake system.

Fitment & Compatibility
The 1.10-inch working width must suit the caliper, while the hat centers the ring on its 8.25-inch register. Check the 12 x 8.75-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.
