Wilwood Right Burnished GT Dynamic Rotor, 12.19 x 1.25-inch, 7.77-inch Lug Mount

Factory burnishing is applied to this right-hand 12.19-inch GT rotor for the dynamic lug-mount system. Its 1.25-inch section and 7.77-inch interface identify the specific ring, distinct from the larger-diameter rotors using a similar retention method. 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

Requires the specified dynamic-lug hat or carrier and its retaining hardware. The lugs accommodate the intended mounting movement; conventional bolt-hole hats are not interchangeable. Check the rotor's diameter, working width and registration against the complete caliper assembly. Select pads and operating duty to suit the rotor material and the intended brake system.
