Wilwood Drilled Steel Racing Rotor, 12.00 x 0.31-inch, 7.62-inch Threaded Mount

Built for limited-duration braking in drag or dirt competition, this solid steel rotor has drilled faces and a black coating. Its eight threaded mounting points on a 7.62-inch circle require the corresponding attachment hardware, not a standard 7.00-inch hat. This component comes from Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with compatibility determined by the complete brake assembly.

Fitment & Compatibility

Use only in a suitable drag or dirt racing assembly with controlled sustained temperatures. The eight 5/16-24 mounting threads require the matching 7.62-inch-circle attachment; this is not the eight-on-7.00-inch through-hole version. Not for street use.
