These are the wheels on my car and I think they are my favorite wheels I have seen on an fbody, but I don't know what they are called (if they even have a specific name)

 

Concave Formula 16x8 rims? I also used to like them a lot, and they look really good when polished

EDIT: Actually those are 15's aren't they? Look like they have quite a bit of sidewall...then again I am used to seeing my 17s/18s, lol

 

Just standard base model (turbo fin I belive?) 15" wheels. If you like them then great, I'm sure you'll be able to find plenty of replacements if you bent one.

 

Yeah, those are the stock Firebird wheels. 15x7. I personally don't like em much, but to each their own...

 

GM called them “high tech” rims… there are the concave and convex 16” versions as well as that 15” version. There are also versions of them that were used on assorted smaller cars that will not fit on f-bodies.

FWIW, the 16” convex ones are super heavy (my formula has them stock) while the 15” concave ones are really pretty light (I use a set of them to mount my drag tires and they’re almost as light as a real race rim)
