Wilwood Right GT 36-Vane Rotor, 12.00 x 0.81-inch, Plain-Finish Slotted Iron

This GT rotor increases the friction diameter to 12.00 inches while retaining the 0.81-inch width and eight-on-7.00-inch mounting family. The right-hand curved-vane ring needs a caliper position and pad sweep matched to that diameter. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Selection must account for the entire brake system.

Fitment & Compatibility

This ring is a component of a matched brake system. Confirm 0.81-inch rotor clearance through the caliper, the 12.00-inch radial envelope and the separate hat's 8 x 7.00-inch attachment. Its 6.38-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.
