C5 Z06 Wheels on my 88 trans am?

i was looking around for new wheels from my trans am, i am running the gta 16s on front and back, all 4 are fronts. what looks best for running corvette C5 z06 wheels? fronts 17x9.5 and rears 18x10.5 or both front and back with the 17s? i want a clean look, my car is totally stock suspension wise, and i know i need to run spacers with these wheels but what size spacers? thanks

I think it's 2" spacers all around.
I think I'll be doing theses wheels as well, 17" all 4 corners.

Re: C5 Z06 Wheels on my 88 trans am?

I went with 17X9.5 front and 18X10.5 in the back in C7 Z06 wheels. In my case I had a slight clearance issue in the front with the tie rod. So I had to get an aftermarket tie rod that would clear the rim. If I had known ahead of time I probably would have gone with an 18X9.5 up front. Not sure if the C5 wheels will present the same clearance issue.

2" spacers should be correct.

The last picture is after I lowered the car a bit. The factory ride height was just a little to tall for my taste with the new wheels.

Re: C5 Z06 Wheels on my 88 trans am?

I think lowering springs would work fine. I went with Ground Control Weight jacks so I could adjust the ride height and not have to guess where a lowered spring would set it. As long as you get the right springs there shouldn't be an issue.

Here's the ones I bought: https://www.oewheelsllc.com/18-Fits-...0-5-17x9-5-SET

I also ordered blank center caps and had a local laser engraver put the bird logo on them.
