Sure it’s called a concept, but you can fully expect something just like this out on the track for the Grand Am Koni Challenge racing series. The GS stands for GS racing class, where the Camaro will be chasing down cars like the Porsche 997, BMW M3, and the Ford Mustang GT. The GS Racecar goes for light (carbon fiber hood, trunk lid, doors and fenders) and powerful (small block LS3 V-8 engine).
