Product details

Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

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.
