Wilwood Front Superlite 6R Brake Kit, 12.88-Inch Drilled/Slotted Rotors and Black Calipers — Ford Mustang Five-Lug Spindles (1994–2004)

The 12.88-inch SRP rotor pair gives this Mustang front kit drilled and slotted friction surfaces. Black Superlite calipers and BP-10 pads are supplied with the radial brackets; the original spindle and model-specific restrictions still determine fitment. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together within a properly matched 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.
