Wilwood 1.25-inch Wide Ultralite Rotor with 11.75-inch Diameter and Eight-Bolt Mount

This 1.25-inch-wide Ultralite casting provides a vented iron friction ring for an 11.75-inch brake assembly. Straight vanes permit either rotational direction, while the eight-bolt mounting flange must match the separate hat or hub. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized components are selected around the requirements of the whole braking system.

Fitment & Compatibility

For a matched street or moderate-temperature competition brake assembly. Confirm the hat's attachment circle and register, the caliper's rotor-width capacity and the full pad sweep. A rotor ring does not establish vehicle or axle compatibility by itself.
