The Z06 suspension is nothing to scoff at. In many ways its a much better setup than BMWs. The E92 isn't likely to make up time due to handling.
Other note, its vastly easier to get power down in the Vette simply because it got a lot more rear tire to put the power down.
235 / 265 tires
~8.1 lb / HP
~14.6 lb per mm tire
275 / 325 tires
6.2 lb / hp (~30% advantage)
10.4 lb / mm tire (~40% advantage)
That doesn't take into account the lower CG and better camber control of the suspension that keeps more of the tires in contact with the road.
