The newer 2011-2012 GT500's with the all aluminum motor handle much better,(suspension improvements too) and don't heat soak quite as bad. The performance Package has a 3.73:1 rear axle, Goodyear Eagle F1 SuperCar tires, 19-inch wheels in the front and 20-inch wheels rear. I will try to dig up the last test Car&Driver did on the road course comparison between makes but it was much quicker than the previous cast iron GT500 models. Not saying a Corvette beater, but better.
