Product details
The left factory-burnished GT ring retains the 13.06-inch diameter and 1.25-inch working width. Its slotted Spec-37 friction surface and larger dynamic-lug interface are selected together for the matching race or street brake arrangement. Wilwood Engineering, established by Bill Wood in 1977 and based in Camarillo, California, designs and manufactures disc brake systems. Its component range spans brake rotors and calipers alongside master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. The complete brake system governs which components belong together.

Fitment & Compatibility

Check the rotor's diameter, working width and registration against the complete caliper assembly. The listed duty is street use through moderate-temperature competition.
