Product details
The left-hand floater version combines a drilled-and-slotted service ring with its own parking drum. A 5.00-inch center and specialized hub-attachment pattern separate it from ordinary five-lug slip-on rotors of the same diameter. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc brake systems and their calipers, brake rotors, master cylinders, valves, fittings and brake lines. Across motorsport, street-performance and specialized applications, these components must be matched as parts of a complete braking 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.
Manufacturer reference: Wilwood rotor specifications
Choosing a rotor involves more than its outside diameter. PMB Performance's 20-plus years of brake and parts experience can help you check the component against your existing assembly.
