do 20 inch rims fit
Dont think so. I think you'd have to change too may parts for it to be worth your while.
yes i have 20s on my 2001 camaro its the same space as your firebird they will fit
keep in mind you will have to get lower profile tires. this does decrease your ride comfort noticeably. it also looks very cool if it works. :D sometimes ya gotta sacrifice comfort for styles, right?
Just don't do it. It looks tacky as all hell. Focus your money on something worth it like an engine swap or a custom turbo set up if you have the 3.8L. All those tires do is ruin your ride and reduce the safety of your vehicle. If you want to swap tires on a Firebird, throw a set of 18x11s on a Formula or T/A so it can really hug the road and GO!
18s are better....not only do they look more proportional to the vehicle (and better) they will give better performance.
