Ok since I'm never going to find an original set of turbo cast/aero wheels at an affordable price, I determined that getting a set of reproduction 79-81 Turbo Wheels, and painting the centers black, might be a good alternative.

These are 15x8 wheels, with 4.5 inch backspace (or 0 offset).

I've seen people put 2nd gen Snowflakes on, but I want to 100% confirm this.

I know the original Firebird 20-slot wheels were 15x7, but I don't know the backspacing (can't find it in search)

Classic is having free shipping sale today so I want to pull the trigger if they'll fit.

Yes these will fit just fine, They have the same back spacing as the snow flake wheels from the same gen 2 cars and they fit fine on the third gen. I know this because 20 years ago I was really into 2nd gen Trans Ams and swapped out wheels on a regular bases. But I know the turbo wheels on the T/A 15x8s and I ran 265,50R15s front 295,50R15 rear with out rubbing, But could not run those on the snow flakes with out it looking stupid,
I would say go for the new wheels.

 

Thanks! If they don't fit I'm sending you the bill!

 

That's cool then you can ship them to me, I know they would fit on my third gen and I could use some wheels to but drag tires on.
