Product details
The GT version uses asymmetrical slots without the SRP cross-drilling. This right-hand 14.25 x 1.10-inch Spec-37 rotor combines curved vanes with individual balancing for a correctly matched high-temperature brake assembly. 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
Select the separate hat for the 12 x 8.75-inch rotor-attachment pattern and 8.25-inch register. The 14.25-inch friction diameter and 1.10-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.
