Modified Chevrolet Corvette Stingray, Camaro, SS at 2013 SEMA Show

NASCAR racer Jeff Gordon provided his input on the SS performance sedan concept that rides on a lowered suspension and is fitted with upgraded brakes and a Borla exhaust system. The 415-hp 6.2-liter LS3 V-8 is untouched, but the exterior is customized with a new grille, satin paint, 20-inch rims, and a carbon fiber spoiler. Inside, there are perforated suede seat inserts, a flat-bottom steering wheel, and a pedal kit from Chevrolet Accessories. Chevrolet will show off three examples of the Corvette Stingray, with two inspired by the East and West Coast. First is the Corvette Stingray Convertible Atlantic concept, which gets upgraded floor mats, suede interior surfaces, chrome rims, Fusion Gray headlight housings, and a body kit finished in Carbon Flash Metallic paint. Chevrolet says the concept's modifications are meant to resemble the "details and refinement of a private jet" and some upgrades are available through Chevrolet Accessories. Next is the Corvette Stingray Coupe Pacific concept, what starts life with the Z51 package and Torch Red paint. Mods include satin black wheels and Carbon Flash exterior accents.  The third C7 on display will be the Corvette Stingray Gran Turismo concept, which is essentially a real life version of the car featured in Gran Turismo 6 video game. The extensive list of mods include metallic blue paint with graphics, a carbon fiber body kit, a new front grille, yellow-tinted headlights, a custom flat-bottom steering wheel, and racing harnesses for the front seats. The COPO Camaro returns for 2014 and will retain is super low production run of just 69 units. The hand-built COPO features racing essentials including a roll cage and modified suspension. The car at SEMA is fitted with the supercharged 350 engine, though the 427, and naturally aspirated 350 and 396 engines will still be available.  The new 2014 Camaro Z/28 will be on display and not surprisingly Chevrolet is leaving this car untouched. The Z/28, which recently made headlines thanks to its 7:37.40 lap time on a rain-soaked Nurburgring road course, is powered by a naturally aspirated 505-hp 7.0-liter LS7 V-8. It's also lighter than a Camaro ZL1 thanks to lightweight wheels and a thinner rear-window glass. While the Z/28 is unmodified, the following four Camaros will sport custom bits and items from the Chevrolet Accessories and Chevrolet Performance catalog.  First up is the Chevrolet Performance Garage Camaro concept, which is based on the SS, but gets a mix of parts from the Z/28 and ZL1. Other mods include a ground effects package, graphics, and a helical differential. The Chevrolet Performance Camaro V-8 concept also features Z/28 and ZL1 bits and an even longer list of cosmetic upgrades. In addition to Chevrolet Accessories 45th anniversary wheels, the concept features RS headlights and taillights, blacked-out exterior accents, and custom soft-touch interior trim. The Chevrolet Performance Camaro V-6 concept gains components from its eight-cylinder siblings including the SS' Brembo brake kit and 1LE suspension components. A Borla exhaust system and upgrades from Chevrolet Accessories and Chevrolet Performance complete the mods list. Finally, the Camaro Spring Special Edition is a production-ready package that will soon be available in showrooms. This Camaro features Summit White paint with blue accents (same color theme for the interior), ZL1 spoiler, 21-inch rims, HID headlights, and special floor mats. The Spring Special Edition will be available with a 323-hp V-6 or 400-426-hp V-8 engine.
