Product details
Red Dynapro 6 calipers and 12.19 x 0.81-inch SRP rotors distinguish this Roadster Shop front system. The calipers use 1.62/1.38/1.38-inch piston bores, and the supplied brackets locate them at the specified upright and steering-arm mounting points. 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
For the Roadster Shop Mustang II front upright, using the five-on-4.75-inch hub arrangement specified by Wilwood. This Dynapro 6 package uses 12.19-inch rotor assemblies, so match its wheel diagram rather than a different Roadster Shop brake option. Verify the steering-arm bracket installation and use the register adapters and shims for alignment. The original Ford vehicle name or year does not establish compatibility with this custom spindle. No hubs, spindles or flexlines are supplied; select hoses that remain clear and slack enough across steering and suspension travel. 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.
