Product details
The 5.98-inch radial pattern identifies the attachment layout of this Wilwood Forged Narrow Superlite 6R. This right-hand red caliper has 6 pistons, 1.75/1.25/1.25-inch bores and a 1.10-inch nominal rotor-width specification. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake 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
The bracket must center the caliper over the rotor and locate the friction material at the correct radius. Check hose routing and bleed orientation through the full suspension and steering movement.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement 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.
