I've got a stock 90 gt. Will 18x9's fit?
I'm sure there will be a little massaging required...any tips before I go spend a few thousand on suspension parts and new wheels and tired would greatly be appreciated!
Yeah, they should. You'll want about 6.5" back spacing. Go with a 245/40/18 up front, and a 275/35/18 out back to get closest to stock diameter. You could maybe squeak out a bit more on both, but you're on your own at that point. Try flipping the quad shocks, which should give you the clearance you need, and if they don't rub anything leave 'em be. You may have to roll or cut the rear fender lips and take a hammer to the inner tub as necessary. It won't take much. If the quad shocks do rub, then you can remove them, but that may, probably will, induce wheel hop under heavy acceleration with a sticky tire. That takes parts and knowledge to get rid of, and we can help you, but it may not be worth it to get adjustable control arms, set pinion angle, reinforce torque boxes, etc... Or, if it's just a cruiser/show car, then you might not care to launch hard.
I've got 255/40/18s up front, and 285/40/18 on one of mine with stock tubs, but then again a lot of stuff has been done to make that work, and they still rub a bit up front on full compression.
What suspension parts are you buying? I can't really think of anything with suspension mods that would negate 18x9's but I just have to ask anyway.I've got a stock 90 gt. Will 18x9's fit?

Was just prioritizing. Nothing special, but new shocks struts, springs, etc.What suspension parts are you buying? I can't really think of anything with suspension mods that would negate 18x9's but I just have to ask anyway.
Kinda sorta... definitely helps, but no guarantee. Another thing to get right, perhaps the most important, is pinion angle, which can't be done unless you're lucky or you have adjustable control arms. The point is, if they fit, you must acquit... er... you should just leave them in place as they can only help. Or if you've got a drag radial or slick handy, make a few test passes and see if you get wheel hop. Or, just throw 'em on the shelf and if you get wheel hop, you can put them back on. Just because you don't get wheel hop on an all-season doesn't mean you won't with a stickier tire. I've had plenty of foxes without quads and without wheel hop. Then again, the one I just bought does wheel hop (stock suspension except adjustable shocks), and I've found free quads and plan to put them on it.I've never ran quad shocks on any of my Mustangs and never once had an issue. Nobody I know with a box body runs there quad shocks. They are only there to keep the rear end from rotating up and down but a good set of control arms and poly rear end housing bushings eliminates that
