I have 16 x 7 VOXX Monza wheels- the offset is 38 mm which improves steering effort while cutting back the Kick-back. Sadly, Voxx stopped making them back a few years ago- but the size is perfect. I am running 205/55-16 up front and 225/55-16 in back (these were sizes used by many popular cars back in the 90s- so lots of options in these sizes). The tires are General G-Max all-season tires which rate very favorably in Tire-Rack testing and are cheaper than most. Make sure you pick wheels that are light- I eliminated 3 lbs from each rear wheel and 6 lbs from each front (205 vs 215 previous size)- and the car went from driving like a truck to driving (basically) like a new car...

(Additional note; Looking for wheels- you can look for Subaru WRX 2000-2006.... although the offset is more- it will help with steering effort/kick-back in front...in back you can use longer studs and aluminum spacers to move the wheel-tire out a bit)

A quick note about Subaru wheels... From the factory, they have a smaller centerbore hole. Will need to be bored out to 57mm to fit the Fiero.
LOTS of older VW wheels have the correct bolt pattern (5x100), centerbore, and offset to fit a Fiero.
PT Cruiser and Neon wheels should also fit. (I've seen the 15" Fiero lace wheels on a Neon. Looked really good. )

Edit - I also posted in your Farcebook thread, regarding sourcing a decklid and spoiler.
Welcome to our obsession!
