Wilwood Front S197 Mustang SRP Conversion — Red Superlite Calipers, 14-Inch Rotors (2005–2014)

Red Superlite calipers and 14-inch drilled/slotted rotors make up this Mustang front brake conversion. BP-10 pads and installation hardware are supplied for the specified factory hub arrangement, with brake-hose brackets addressed by the separate flexline kit. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems and components since Bill Wood founded the company in 1977. Its work spans motorsport, street-performance and specialized applications, with a product range covering master cylinders, calipers, brake rotors, valves, fittings and brake lines. These parts must be chosen for the requirements of the entire brake system.

Fitment & Compatibility

The 14-inch red SRP assembly uses the S197 Mustang's documented stock-offset front hub arrangement. Verify the exact 2005–2014 model and factory brake configuration, including any Boss 302, Bullitt or Shelby qualification in the table. Its wheel-profile check comes from DS521, and the original dust plates may have to be removed. The hydraulic connection uses separate front kit 220-9111, whose new line brackets reuse the prescribed factory hardware. Check clearance and routing before evaluating the completed brake system.

The table below gives the detailed vehicle coverage; match the individual entry and each referenced note.
