Wilwood Right Heavy-Wall Fifteen-Inch GT Rotor, Plain Finish, 72 Vanes and 1.25-inch Width

A 15.00-inch friction diameter sits around the twelve-on-8.75-inch mounting flange on this right GT rotor. Its 72 curved vanes and 1.25-inch section require both radial caliper clearance and correct axial placement on the hat. Disc brake systems and components are the work of Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. The company designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component selected to match the complete system.

Fitment & Compatibility

Select the separate hat for the 12 x 8.75-inch rotor-attachment pattern and 8.25-inch register. The 15.00-inch friction diameter and 1.25-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.
