Product details

This Wilwood Forged Narrow Superlite 6R is a right-hand 6-piston brake caliper with a black finish for a nominally 1.10-inch-wide rotor. Its 5.98-inch radial mounting centers and 1.75/1.25/1.25-inch piston bores must match the brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

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 mounting-center spacing and bracket offset together, then confirm the pad sits fully on the rotor friction surface. Piston area must suit the master cylinder and front-to-rear brake balance.

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

Ask PMB Performance for help comparing this caliper with your existing assembly. Our over 20 years of experience are most useful when you provide rotor size, mounting details and the current piston configuration.
