Product details
The drilled/slotted version of this Dynapro 6 kit uses black six-piston calipers and 12.19-inch iron rotors. Its SRP discs have 32 straight vanes and mount through aluminum hats to the retained Roadster Shop hubs. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves 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.
