Wilwood Right GT Lightweight Rotor, 11.75 x 1.21-inch, Plain Slotted Finish

This right-hand GT rotor combines the 1.21-inch section with asymmetrical face slots. It is balanced but unburnished, so rotor preparation and pad bedding remain part of commissioning the correctly matched brake assembly. Since its founding by Bill Wood in 1977, Wilwood Engineering has designed and manufactured disc brake systems from Camarillo, California. The product range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized installations. Each selection must meet the requirements of the complete brake system.

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 1.21-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.
