I just got a pair of Z06 wheels for my 1992 Z28 and found out that the back wont fit unless I use some wheel spacers. And it looks like it will need up to 3" to make the Z06 wheels work. The wheels are 19.10 in the rear and 18.8.5 in the front. I'm thinking about trading them off to anyone with a nice pair that is wide just send me a pic of what you have.
