Is it possible to have 18" rims on a Fiero lowered about 2 inch with McLaren springs??
Most Fieros have 17 inch, so I wonder why no one puts 18 inch on the Fiero. Is there any reason for this?
My Fiero is (Yeah you can guess if you read the username) a Black GT (Fastback) from 1987. I now have 215/60/15 at the rear and 205/60/15 at the front (This the original rim/tire size as far as I know). I know have Alessio Giro 15 Inch rims but I want 17 or 18 inch.
Was thinking about 225/40/18 at the rear and 215/40/18 at the front. I think this is about the same diameter as the original wheels so I don't think it will be a problem or do I mis an important detail here, like the rim width or something?
Any tips? What about the offset. I heard it is somewhere between 35 and 45 for Fieros is that true??

I have 18's on my convertible....there are several people running 18's and even a few 19's (there is a guy with 20's on the rear!), so I don't see a problem with using them on your '87.
I have 18x8.5 rims all the way around and the stock front lower control arms had to be notched for clearance. I think if you use skinnier rims there won't be an issue.....same thing with an aftermarket suspension (Held coilover conversion, for example). The guy who is running 19's up front and 20's in back is using Held's sport kit and did not have to modify anything to get his rims to fit.
BTW.....I am using 225/40-18's up front and 265/40-18's in the rear. From the sizes you mentioned I do not see any problems (since they will likely be mounted on rims skinnier than 8.5").
Depends on tire size (sidewall height). I cant lower a fiero over 2 inches around here. Speed bumps are 3" high and Fiero floor is only 5" off the ground from the factory. My vette bottoms out and drags over them all now.

Okay, maybe I'm just an ignorant old fogey - but I don't get it.
Why?
Just wondering what are the reasons to run wheels larger/smaller than 15inch?
A couple reasons. One being the looks, a fiero looks fairly modern, but it's wheels don't. And IMO they just don't look very good period, but that's just opinion.
Another reason is handling. Usually lower profile tires are associated with bigger wheels, and low profile tires are usually better for handling. Also, I think you can fit wider wheels on a fiero if they are also larger in diameter.
The reason I want bigger rims like 18 inch is the looks. I have 15 inch Alloy wheels now from Alessio which is already looking very good, but it will look even better with 18 inch.
If the handeling will also improves that will be even better. I lowered my car about 2 to 3 inches now, that is also a very big improvement in corner-handeling. Now finish the looks with 18 Inch.
The correct (big) Rims can make or brake the looks on your car, so in my Opinion this a very important upgrade. And even with Ugly 18 inch rims you car still looks ugly so not all 18 Inch rims will be automatically an improvement.

I have Ebach front lowing springs 2" with one coil cut off. I also have poly bushings. The rear I'm using the coil over kit from ground control. nice cheap setup
Your speedometer will not be accurate, but it can be pretty close. I think it is important that my speed-gauge will still be accurate, so that is why I use the tyre size calculater. I found several on the internet.
If I use 215/40/18 at the front speed gauge will be 0,4% to slow and 225/40/18 at the rear which will read 0,3% to fast on the speedgauge. This is an acceptable range, won't get me into trouble with the speed limits.
225-40-18 frt & 245-40-18 rear
