GM has to juggle with the Z though and that's one thing they are kind of in a pickle with.
They cannot make it outperform a Z06(which I don't think they will even come remotely close)
But it needs to be a legit player STOCK with the GT500(make it a drivers race pretty much) and make mincemeat of the 2011 GT.
They need to make it hardcore enough so the hardcore guys will go for it, and make it honestly better than a Corvette Coupe(at least in my opinion) but less than the Grand Sport.
There's a lot of marketing that has to go behind this
because if they eff it up they will kill sales of another car.
