Wilwood Right Black GTB Rotor, 15.00-inch Diameter and 1.25-inch Heavy Wall

Black electrocoat distinguishes this right-hand GTB version of the fifteen-inch heavy-wall ring. Its 1.25-inch Spec-37 section and 72 curved vanes require a matching twelve-bolt hat and correct rotational orientation. 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

The 1.25-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.
