Product details

A six-piston differential layout provides 5.40 square inches of effective area in this left-hand Wilwood AV6R. The selected unit has stainless pistons and an anodized forged body; its special bracket offset must suit a nominal 1.30-inch rotor-width assembly. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Match the 7520 pad shape and rotor friction track before committing to the installation. Neither the AV6R name nor 7.09-inch center spacing establishes the required offset, so compare the caliper drawing with the bracket and rotor together.

PMB Performance brings over 20 years of experience to brake-component selection. Share the installed caliper, rotor size and mounting arrangement so the relevant dimensions can be compared.
