Wilwood Front Black Six-Piston Mustang Kit (2005–2014) with 14-Inch GT-Slotted Rotors

The 14-inch GT rotor assembly is paired with black six-piston Superlite calipers for this Mustang front package. It requires the DS521 wheel envelope and may require removal of the original dust plates for rotor clearance. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines as part of its disc brake systems and component range for motorsport, street-performance and specialized applications. Each component must suit the requirements of the complete brake installation.

Fitment & Compatibility

For the listed 2005–2014 Ford Mustang front applications with five-lug, stock-offset hubs. The table separates base, GT, Bullitt, Boss 302 and Shelby GT500 configurations by year. Confirm the exact factory package and wheel measurements before ordering.

The 14-inch assembly needs the wheel clearance shown in DS521; nominal 18-inch diameter alone is insufficient. The original dust plates may need removal. Order front hose kit 220-9111 separately and install its replacement line brackets using the specified factory hardware.

Use the fitment table below to confirm the exact model, year, trim and all numbered application notes.
