its a 250rwhp difference aerodynamics had nothing to do with it. The gt500 would have to be 1500-2000lbs heavier than the c6 for weight to be an excuse. But a 75 shot would make perfect sense it would put Marshall at about 515rwhp and 540rwtq. Sorry Marshall but their is no way just like you hanging with a 570rwhp kb z06 not gonna happen NA.Originally Posted by qsz
