Wilwood Drilled Front Disc Conversion for 2005–2014 Ford Mustang BMR Suspension, Black Six-Piston AERO6 Calipers and 14-Inch Rotors

Drilled-and-slotted rotor rings replace the GT rings in this black AERO6 front package for the specified BMR-equipped Mustang. The conversion retains the documented factory hub interface and uses separate aluminum hats, bracket hardware and supplied flexlines. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It develops disc brake systems and components, designing and manufacturing calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. A correct conversion matches those individual components to the complete braking system.

Fitment & Compatibility

Confirm that the installed BMR suspension arrangement matches the application, rather than selecting solely by Mustang model year. Check hub seating, mounting clearance and the full 18-inch wheel diagram in DS1054 before connecting the included hoses.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
