One week after revealing its SEMA 2018 Focus ST and RS lineup, Ford is now showing its Vegas-bound Mustangs. At the moment (and this likely won't change) none of the Mustangs you're about to see will be sold in dealerships, but all of their added-on parts and accessories will soon be readily available, if not already. SEMA is an annual tuning and accessories show that takes place in Las Vegas, but the show isn't open to the general public.Instead, it's more of a trade show, but mainstream automakers still bring some pretty interesting offers.

First up is the Mustang Fastback by Air Design, which features a full body kit, including a front bumper replacement, side skirts, a rear lower skirt, fender vents and an aggressive rear wing. Power comes from the familiar 2.3-liter turbocharged four-cylinder paired to the new 10-speed automatic. The body is covered in Sherwin Williams custom silver paint with black stripes, while the interior has Recaro leather seats.

Next up is the DRAGG Guardian-themed Mustang EcoBoost. Drag Racing Against Gangs and Graffiti (DRAGG) is a non-profit youth-oriented automotive after-school program. Equipped with a six-speed manual, Borla exhaust, Air Raid intake, and Ford Performance lowering springs, the exterior has 3D graphics, Petty's Garage rear spoiler, and Federal Signal emergency lighting by West Coast Lights and Siren. The interior is covered in Katzkin leather.

MAD Industries' 2018 Mustang convertible is also powered by the EcoBoost engine and six-speed combo, though the engine has been re-tuned with a Ford Performance intake and exhaust for added power. Outfitted with a set of massive 20-inch wheels, there's also an APR Carbon Fiber Drag Wing for improved downforce and a more aggressive look. The interior has Braum Elite-X Series Racing bucket seats and, among other add-ons, 3M Crystalline automotive window films and a Classic Design Concepts light bar.

Of course Roush would bring a Mustang to SEMA. The longtime Mustang tuner created this custom-built wide-body Mustang featuring styling cues from the historic 1970 Boss 429. The exterior is finished in a commemorative hue of Ford's Grabber Green. Equipped with various race-inspired carbon fiber parts and Vossen forged wheels, Roush also opted for the 5.0-liter V8, paired to that new 10-speed slushbox. The interior reveals Recaro Racing seats, Watson Racing roll cage, and SPARCO 4-point racing harnesses.

Tucci Hot Rods has opted to tackle the Mustang V8 fastback's aerodynamics. Its goal was to reduce drag and increase power. Cool. It has a Hellion twin-turbo kit, DEI exhaust wrap, and Mishimoto radiator, transmission cooler and oil cooler. The exterior features an aluminum pro mod wing and rear diffuser, 3D-printed hood vents, and even a Stroud parachute.

Speedkore Performance Group opted to go with the Mustang GT Convertible, featuring many carbon fiber aero touches, upgraded suspension, and V8 engine enhancements. The exterior trim of brushed aluminum accents, is all handmade while the interior is covered in Bomber brown leather. Note the carbon fiber roll bar with aluminum trim, a deliberate retro touch. Ford Performance says "the tonneau cover is a modern throwback to classic speedsters and race cars from the 1930s."

Lastly comes a Mustang done by professional racer Brad Deberti. This 2018 Mustang GT is fitted with a Roush supercharger and a widened body, complete with 18-inch rear tires and Forgiato wheels. The front end has a DeBerti grille and Bullseye Retro custom headlights. Instead of the slushbox, there's a six-speed manual driving the rear wheels. There's also a Watson Racing independent rear suspension with H&R Performance adjustable springs and struts. The car is finished off with red-painted brake calipers and a Borla exhaust.
