Maybe it's my inexperience, but the GT class seems more reasonable than the GTS. It seems more "logical" to place the car against 911, M3, 360 Modena, TVR, & Morgan instead of the GTS class against Saleen S7, Ferrari 575, Viper GTS-R, Corvette C5-R, Pagani Zonda, and others. Just the list seems quite intimidating. Then again, I recall that a 350Z was going to compete in GT. Is that a reason for not doing GT?
