After the Mustangs and Fiestas, Ford has now revealed four of the finest customized Focus ST models headed to this year’s SEMA show in Las Vegas. And they couldn’t be more different. One is inspired by road racing, the other by Formula One, another by rallying, and another one by Southern California car culture.

Let’s begin by the Californian model, pictured above, which is probably the only Custom Ford Focus ST from this lineup that the owners can really relate to and maybe get some ideas from. It features powertrain upgrades, including Banks Power straight-shot water-methanol injection system and iQ Man-Machine Interface, a custom paint job with carbon fiber parts, 19-inch Rotiform wheels wrapped in GT Radial Champiro tires, and Sparco seats with Schroth Racing five-point harness.

Next up we have the F1 wannabe, the Green Filter USA 2014 Ford Focus ST. This one features a cool vintage Team Lotus livery including some body work to mimic the F1 racer including exhaust outlets on the custom exhaust kit. Another highlight of this vehicle is the set of wheels from American Racing Wheels wrapped in Falken tires.

Drag Racing Against Gangs & Graffiti (DRAGG) has come up with a rally racing version of the 2014 Ford Focus ST. Along with the special law enforcement wrap, the car comes with a Borla-designed high-performance bolt-on cat-back exhaust with dual 4.5-inch polished stainless steel tips, wheels from Motegi Racing, suspension from Eibach Springs and Wilwood Engineering brakes.

The coolest of the ST bunch is this Gulf-livered model. Built by Universal Technical Institute in partnership with Neil Tjin of Tjin, the car features the blue and orange livery of Gulf Racing, plus custom dual-side exhausts exiting from an intercooler kit by Vortech Superchargers and a high-flow catalytic converter from Motiv Concepts that gives the driver more ponies. A set of 19-inch wheels with Falken tires wrap up the package.
