Product details
For a brake system using a 1.10-inch-wide rotor, this Type III anodized Wilwood Forged Narrow Superlite 4R provides 4 pistons with 1.38-inch bores. 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.
The narrow Superlite 4R has four pistons, radial attachment and removable center bridge access to type 7416 pads. Check the specific rotor-width version before ordering another caliper from the same family.

Fitment & Compatibility
Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
