Wilwood Right GT Rotor, 11.75 x 0.81-inch, 36 Curved Vanes and Slotted Face

GT slots and a balanced Spec-37 casting define this right-hand 11.75-inch rotor. The unburnished 0.81-inch ring is selected for its own thermal duty and mounting dimensions, with bedding completed as required by the installed pad compound. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.

Fitment & Compatibility

Select the separate hat for the 8 x 7.00-inch rotor-attachment pattern and 6.38-inch register. The 11.75-inch friction diameter and 0.81-inch section must agree with caliper placement and pad sweep. This mounting circle is independent of the vehicle's wheel-stud pattern. Select pads and operating duty to suit the rotor material and the intended brake system.
