Product details
Red finish and 1.75-inch bores distinguish this Wilwood Dynapro Narrow Lug Mount configuration. It is a 4-piston brake caliper for 0.38-inch-wide rotors, with 5.25-inch lug attachment centers. 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.
This narrower-outboard-profile Dynapro uses four pistons with a 5.25-inch lug pattern. Top-access type 7812 pads and internal fluid passages support service, but the reduced profile must be checked against the actual wheel and rotor-hat dimensions.

Fitment & Compatibility
Use the intended rotor and bracket dimensions to establish compatibility. The chosen pad compound, master-cylinder volume and brake balance must be considered with this caliper’s piston sizes.
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.
