Wilwood HP Plain Rotor, 12.19 x 1.10-inch, 32 Straight Cooling Vanes

The 1.10-inch HP ring uses straight vanes and a plain pad-contact surface. Its 6.45-inch registration is a critical distinction from other eight-on-7.00-inch rotors, even where outside diameters look similar. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. 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. Selection must account for the entire brake 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.
