I see this question from time to time. I just stumbled across this.

Note... It shows the Pontiac Vibe having a 57.1 mm centerbore. I think that's incorrect. It shares the Toyota Matrix hubs, at 54.1 mm.
I didn't notice any other glaring errors or omissions.

You can also look up other patterns, if you feel so inclined. Cool site, all around.

I was pleasantly surprised when I bought my '98 JDM Subaru WRX STi several years ago, to discover that aftermarket wheels I had bought for my Fiero(s) could be used on the Subie with the appropriate sized hub-centric rings. (The Fiero's hub center bore size 57.1mm is whereas the Subie is 56.1mm.)

I believe that specifications like rim width, backspace and offset also need to be considered

Absolutely.

To further elaborate on that, and cut to the chase, it appears that Volkswagen (new) Beetle wheels are perfect (IMHO) for 84-87 Fieros, unless you want to go nuts.
17x7 or 17x8, 35 mm offset. Those will work on either end, will not hit anything, will look good (like not stick out too far), and can be rotated if you choose the same tires for all four.
Of course, if you want staggered, you might have to shop a bit.
Others may differ, depending upon preference.
