Product details
For a brake system using a 1.10-inch-wide rotor, this red Wilwood Forged Narrow Superlite 6R provides 6 pistons with 1.75/1.25/1.25-inch bores. Left-hand mounting is specified. The caliper attaches on 5.98-inch radial centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
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.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
