Wilwood Rear Right Floater SRP Rotor, Black 12.19-inch with 5.00-inch Center

This right rear SRP rotor accommodates the large center of a compatible Strange-style floating hub. The 5 x 5.75-inch attachment and 1.91-inch hat offset locate the 12.19-inch friction ring over the matching rear brake assembly. 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 the matching Strange-style floating-hub rear brake system. The five-on-5.75-inch circle is the rotor's hub attachment and the 5.00-inch center clears the floating hub; neither dimension establishes a general wheel pattern. Verify the 12.19-inch caliper position and 7.24-inch parking-brake drum.
