Product details
This black DynaPro is the thin solid-rotor configuration with four 1.75-inch stainless pistons. The forged housing has a nominal 0.38-inch opening and 5.25-inch lug centers. It is a caliper component for a system designed around the selected pad shape and rotor, with a published piston area of 4.80 square inches. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Match a rotor 0.25–0.38 inch thick and confirm the full diameter and pad-sweep requirements. The bracket needs the correct mount height and stand-off, not merely matching bolt centers. Inspect wheel and hub clearance around the housing and fitting, then check the intended hydraulic balance before substituting a different-bore caliper.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
