Product details
The large 5.00-inch center clears a compatible Strange-style floating rear hub. This plain 12.19-inch rotor uses a 5 x 5.75-inch hub-attachment arrangement and a 1.91-inch offset, with the parking drum integrated into the hat. This component comes from Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with compatibility determined by the complete brake assembly.

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.
