Wilwood Solid Iron Plain Rotor, 10.85 x 0.39 Inches, Six-Bolt Mount

This solid iron ring provides a 10.85-inch friction diameter without internal cooling vanes. The 0.39-inch section and six-bolt flange suit a matching compact brake assembly, with plain pad faces rather than slots or drilling. System compatibility is central to choosing a replacement rotor, including its relationship to the caliper, pad and mounting hardware. Wilwood designs and manufactures disc brake systems in Camarillo, California, offering calipers, rotors, master cylinders, valves, fittings and lines across motorsport, street performance and specialized applications. The company was founded in 1977 by Bill Wood.
