Seriously?? Isn't GS a straight production chassis class??
Thought it was too...
Grand-Am website seems to say so, althought who knows when they last updated the descriptions. I didn't try to find the actual rules.
The GRAND-AM Continental Tire Sports Car Challenge features sports cars manufactured from around the world, brought straight from the showroom floor, that race side by side with only minor modifications in the area of safety. Like the GRAND-AM Rolex Series, the Continental Tire Sports Car Challenge races two classes at the same time: Grand Sport (GS) and Street Tuner (ST).
...
The big-bore Grand Sport (GS) class features a rules package allowing exotic international machines like the Porsche 997 and Cayman, Nissan 350Z, BMW M3, Subaru WRX, Audi S4 and others to go head-to-head with American iron such as the Chevrolet Camaro, Ford Mustang GT and Dodge Challenger. The smaller Street Tuner (ST) class is GRAND-AM's offering to the import and compact car crowd, with the Honda Civic Si, MAZDASPEED3, Mazda RX-8, Mazda MX-5, Chevrolet Cobalt SS, Dodge SRT4, Mini Cooper S, BMW 328i, BMW 330i and other eligible models..
