The 3,800lbs is its maxed out weight. Car and Drivers 2011 GT500 PP test car weighed in at 3,751lbs before it hit the track when it pulled 4.1 0-60 and 12.4 in the 1/4 and in the test above showed a huge mph advantage going to the GT500. 119mph is good for mid-high 11's vs 116.5mph for the vette, and Evan Smith just ran a 12.0 in the Florida heat.

If I did want a 2 seater track superstar it would definitely be the vette but I would probably wait for the C7, for me I'm more into drag racing and running low 11's stock on stickys and 10's with a pulley and tune thanks to it fully forged engine, and then when im bored i'll hit Thunder Hill Raceway with my family members that have c5 zo6 and a viper.
