Product details
Red Dynalite calipers and GT slotted iron rotors form the compact 11.38-inch Roadster Shop front assembly. The four-piston calipers use BP-10 pads, with the hat and bracket geometry specific to the Roadster Shop Mustang II spindle rather than a generic Mustang replacement. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications.

Fitment & Compatibility
This 11.38-inch Dynalite kit fits the Roadster Shop Mustang II spindle/upright arrangement. The manufacturer describes a five-on-4.75-inch hub application; confirm the actual Roadster Shop hardware before selecting it for a custom build. It is not a claim of direct fit to a factory Mustang based on model year. Install the brackets at the prescribed steering-arm location, then use the supplied register adapters and shims to center the calipers over the rotors. Existing compatible hubs are retained. Spindles and flexlines are separate, with hose length chosen for the suspension's full movement. Nominal minimum wheel diameter: 15 in; 381 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
