Wilwood Front Mustang Five-Lug Conversion (1994–2004), Black Superlite 6R & GT-Slotted 12.88-Inch Rotors

This black Superlite front kit is sized around 12.88-inch GT-slotted rotors for the qualified 1994–2004 Mustang applications. Six-piston calipers mount radially over separate rotor hats, retaining the factory five-lug hubs and stock offset. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded by Bill Wood in 1977, the company also produces the individual calipers, brake rotors, master cylinders, valves, fittings and brake lines used in these installations. Selection should account for how each component works within the complete brake system.

Fitment & Compatibility

For the listed 1994–2004 Ford Mustang five-lug, stock-offset front spindles. Base and GT coverage is supplemented by specific Cobra, Bullitt and Mach I entries. Observe the independent-rear-suspension exclusions attached to particular 1999–2001 applications in the table; a trim name alone does not override those restrictions.

Retain the factory hubs and confirm the 12.88-inch package against DS513. Wilwood-compatible front flexlines 220-6458 are sold separately. Verify the wheel template, mounting-bolt engagement and the resulting brake balance after assembly.
