Will these fit?
I was wondering if these C6 ZR1 wheels would fit on my GTA? Im assuming that I will need some spacers?

I don't see the offset specs on the 2nd set. And yes, the first set will fit with spacers. The 2nd set probably will too, with the right spacers.
Get a LS1 rear end & you won't need spacers (or much thinner ones) in the rear AND you'll get the bigger/better brakes too.

Re: Will these fit?
The first set is 79mm off set which translates into over 8.5" BS which will require a spacer even with a 4thgen rear unless you want to perform surgery. The second set says C6 backspacing so they're probably even a little worse as they are an inch wider.
