So what are we expecting here for a GT500 advantage? A minimum of a full second and 5mph?
M6 vs M6 I'd say more like half a second, the A6s less than that. Trap speeds maybe 5-7mph. With the combination of 3.31s, 400lbs less weight and 60hp+ more the GT500 will start running away by buses once traction is out of the equation IMO.
