Wilwood Black 11.00-inch GTB Rotor, 0.81-inch Width and 72 Straight Vanes

This GTB rotor adds black electrocoat to the six-bolt 11.00-inch configuration. The 72 straight vanes permit either side, while its 5.59-inch registration and 0.81-inch width remain essential dimensions for the matched assembly. 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

This ring is a component of a matched brake system. Confirm 0.81-inch rotor clearance through the caliper, the 11.00-inch radial envelope and the separate hat's 6 x 6.25-inch attachment. Its 5.59-inch registration must locate concentrically on the specified mounting hardware. Select pads and operating duty to suit the rotor material and the intended brake system.
