Product details
The left-hand member of this GT pair brings a 14.25-inch slotted friction ring to a compatible 1.25-inch-width caliper system. Its balanced Spec-37 construction uses 72 curved vanes and a twelve-bolt mounting flange. For this rotor, the manufacturer is Wilwood Engineering, founded in 1977 by Bill Wood and based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized products are selected to satisfy the complete brake system's requirements.

Fitment & Compatibility
The 1.25-inch working width must suit the caliper, while the hat centers the ring on its 8.25-inch register. Check the 12 x 8.75-inch attachment and radial pad coverage before installation. Vehicle make or wheel pattern alone cannot identify a replacement rotor ring. Select pads and operating duty to suit the rotor material and the intended brake system.
