Product details
The 12.88-inch HD ring retains smooth faces on a heavy-wall Spec-37 casting. This right-hand configuration combines a 1.25-inch working width with 48 curved vanes and a twelve-bolt attachment flange. 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
Installation requires a hat or hub designed for the 8.25-inch rotor register and 12 x 8.75-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 1.25-inch width. The ring alone does not define a direct-fit vehicle or axle application. Select pads and operating duty to suit the rotor material and the intended brake system.
