Product details

A 6-piston Wilwood Forged Narrow Superlite 6R for left-hand installation, this Type III anodized caliper works around a nominally 1.25-inch-wide rotor. Its 1.75/1.25/1.25-inch bore configuration and 5.98-inch radial centers are the principal dimensions to compare. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

The six-piston narrow Superlite has differential bores, radial mounting and a removable center bridge. Type 7416 pads fit the friction cavity, while each rotor-width and piston-area combination must be matched to the complete brake system.

Fitment & Compatibility

Check the caliper-to-bracket attachment and rotor offset before ordering. Changing piston diameter changes hydraulic requirements even when a different caliper shares the same bolt spacing.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.

For a brake system assembled from individual components, PMB Performance brings over 20 years of experience. Contact us with the rotor, caliper and bracket information so we can help check the combination.
