Fitment & Compatibility

Retain the specified five-lug front hubs and factory disc spindles on the listed 1994–2004 Mustang. Check Base, GT, SVT Cobra and Mach I rows, including the chart restrictions, before choosing the brake package. The two-piece 14-inch rotor assembly and radial AERO6 calipers require wheel verification using DS-1422. Braided 18-inch flexlines are included and must be checked for correct fitting size and routing. No hub, spindle, master cylinder or booster is supplied. Inspect the entire front-to-rear brake balance after conversion.
