Kia has something pretty damn awesome on its hands, so it makes total sense to go all-out at this year's SEMA show with a pair of modified Stinger GTs. A Cadenza was also thrown into the mix, but the GTs are the real treat. The first one is the Stinger GT Federation, featuring bold orange exterior paint and body kit accents by Air Design USA. These include aggressive hood vents, rear spoiler and rear diffuser. A set of 20-inch TSW wheels with Falken tires round out the look.

Under the hood, a K&N cold-air intake has been added and, along with the quad-tipped Borla exhaust, generates an additional 15 hp from the twin-turbo 3.3-liter V6. Total output is estimated at 380 hp. Eibach springs, thicker anti-roll bars and a reduced ride height provide an overall sportier look. The second Stinger GT is the Wide Body, courtesy of West Coast Customs. With inspiration from the racing GT cars from the 1970s, the shop added wide fenders and lowered the suspension by 1.4-inches up front and 1.2-inches at the rear. The vehicle rides on a set of 21-inch Keen forged wheels wrapped in high-performance rubber. In addition, there's a lightweight carbon fiber aero kit and rear diffuser, and quad-port exhaust tips.

The interior has custom blue leather seat piping, a gray leather hand-stitched dash pane, and Alcantara-wrapped steering wheel. Lastly, there's the Cadenza Obsidian, also courtesy of WCC. With its lowered suspension, stiffened springs, and custom 20-inch wheels with Cosmic Copper trim, the entire body features metallic black paint with ultra-dark ceramic window tint. A hand-stitched suede dashboard, brown leather seats, and a Harmon-Kardon 630-watt sound system complete the work.
