Product details
The compact twelve-on-7.15-inch attachment distinguishes this right-hand GT rotor from larger-register designs. Its 12.91-inch diameter and 1.26-inch width must both match the brake assembly, with GT slots on the plain-finish Spec-37 ring. Based in Camarillo, California, Wilwood Engineering was founded in 1977 by Bill Wood to design and manufacture disc brake systems and components. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Rotor selection is therefore a decision about the whole brake system and its mating parts.

Fitment & Compatibility
The 1.26-inch working width must suit the caliper, while the hat centers the ring on its 6.33-inch register. Check the 12 x 7.15-inch attachment and radial pad coverage before installation. Vehicle make or wheel pattern alone cannot identify a replacement rotor ring. The listed duty is street use through moderate-temperature competition.
