the car is 2860 pounds , with the conversion im sure it adds a signifigant amount of weight what with the engine, and everything else they have to replace in order to handle 600HP. im sure it weighs just about the same as the corvettes do (3200 lbs). and the tires are 10.6 inches wider on the corvette than on the solstice. i dont doubt that the numbers are correct.
which makes me wonder why mr peabody thinks they will blow the doors off one? i bet the 600hp would beat the 505hp Z06 , but would the 505 hp solstice conversion beat the 505 corvette? if at all certainly not by much.
