Z06 0-60 3.7 sec
GT2 0-60 3.6 sec.....cost 190,000 + (This is Porsche's fastest 0-60 car they currently produce)

I can not find any data to support your 2.9 second claim. Too bad the base Corvette turns faster lap times than half of the 911 series, let alone what the Z06 runs. As far as I can remember, there are only 2 Porsche's that can turn a faster lap time than the Z06, and one was only a tenth of a second faster. Of course every one of those is twice the price...
