We know that at least four Mustangs will join the F-150, Focus ST and Fusion displays at the Ford stand during SEMA. They were designed by four customizing outfits, Ringbrothers, Stitchcraft, DSO Eyewear and a joint effort by Mothers, Autosport Dynamics and RTR.

The Ringbrothers Mustang GT starts with a 5.0-liter V8 and six-speed manual. To that Ringbrothers adds a supercharger, suspension upgrades, Baer brakes and a carbon-fiber body kit. It uses waterborne paint for the exterior, which is better for the environment and meets new standards for low volatile organic compounds. Big wheels with rubber-band tires complete the look.

Stitchcraft, a California-based company that reupholsters boats, RVs and cars, started with a V6 Mustang convertible for its show car. Stitchcraft bolted on a nitrous-injection kit, FlowMaster exhaust, Hotchkis coil-overs and Wilwood brakes. The sleek bodykit was done by 3dCarbon while Stitchcraft took care of the interior.

DSO Eyeware may seem like a funny company to customize a car for SEMA. But a quick look on its Web site shows a custom Ford Explorer and Chevy Camaro convertible. The company makes driving shades as well as stylish frames for the young and famous.

DSO didn't mess around, installing a Whipple supercharger with an intercooler to bump output to 750 hp. An Eibach suspension pins the car to the road and Brembo brakes bring everything to a halt. Bodywork was done by 3dCarbon and Rockford-Fosgate donated the audio system.

RTR, a company that knows its way around a Mustang, took on the final car. Again it started with a V8 GT base car and pumped horsepower up to 650. It also added a track-ready suspension and carbon-fiber body kit. Sparco provided the racing seats and the custom upholstery.
