Product details
This right-hand GT rotor puts a slotted face on the 12.19 x 0.81-inch Spec-37 ring. The 36-vane casting is individually balanced, with a plain finish and eight mounting holes for the separate compatible hat. 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
The 0.81-inch working width must suit the caliper, while the hat centers the ring on its 6.38-inch register. Check the 8 x 7.00-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.
