Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses.

Fitment & Compatibility

Drag or dirt racing use only; not for street use. Confirm the actual mounting method before ordering: Wilwood's dimension table gives eight 0.326-inch holes on a 7.00-inch circle, while its additional notes describe slots with T-nuts. The required hat and hardware must be established from the supplied rotor.
