A forum member PM'ed me asking about the fitment of my wheels, specifically how far they stuck out in the rear with a -35 offset on an 18x8 wheel. Instead of emailing him pictures, I figured I put it up here for reference as wheel fitment is a common point of confusion. The car is an '87 converted to coilovers in the rear. All four corners are 18x8 -35 wheels; tires are 245/40/18 rear, 225/40/18 front.






I feel like -35 is ideal for the rear but the fronts could probably -40 to -48 to look ideal, although I'm not sure if there would be any fitment issues. Maybe someone can chime in. He also asked about how wide of a tire could be run without hitting the coilovers. I can't comment on this specifically as the car is in storage and I don't recall exactly how much space was back there but in my opinion, on an 8-inch wide wheel, a 245 is already 9.65 inches wide. Maybe you could do a 255 or 265 but anything beyond that would require a 9 or 10 inch wide wheel, which would only work dependent on the coil clearance.

Hope this information was helpful!

It would be nice if you could post a top-down photo with the camera lens centered above the front fender lip with the wheels pointed straight ahead. I find almost everyone with wide rims and shallow offsets post photos with the wheels turned or from an angle that doesn't allow a fair assessment of how much they stick out.

I agree, I'll get some later this week. I wanted to provide somewhat of an idea before I could get to my car in storage.


Are the pictures working for anyone else? I show broken links even though I used PIP...

Looks nice! I do agree, the fronts look like they do stick out quite a bit. My Formula has that wider front too, but I still have the 15" wheels. I love the look of the 18"!

SSR Integrals. One of my favorite wheels ever.

Looks great.

There is some sort of front brake conversion on there?

Thanks! I lucked out and found them used in perfect condition on the 5x100 VW wheel forum!

Yes, Grand Am brake conversion with drilled/slotted rotors.

When I did my swap I couldn't find the desired sizes for my car in the Integrals so I bought Mille Miglia MMII's instead.

I think the MMII's looked really good, but I think the Integrals look even better.

That is what leads to the wider front track. You've added ~10mm to each side of the front of the car. In order to counteract that, you need to run a numerically lower offset wheel in back than in front. In comparison to the factory configuration, you're actually running +35mm rear, and ~+25mm front. The Grand Am rotors are like 10mm spacers.

O.P. - looks great, I love 18's and found when I had some that the ride quality was just fine, not harsh at all. Two questions, though (the Fiero I had already had the 18's on it so I don't know any fitment issues firsthand) ; did you have to do rear coil-overs to get them to fit? And, do the fronts rub at all? I'm looking for rims again myself and thought 35 offset would be just about right.
