I have an 87 Formula and would love to see the difference between my rims and the TA rims of that year. Does anyone have photos of the rim differences from year to year? I'm pretty sure the Formula's got the concave rims after 87 and only had the convex rims for one year. Does anyone have pics of the different rims?

 

quick search though the readers rides would answer your question
concave:

convex:


One curves in, the other curves out.

Think of it this way: Concave.. cave.. you go into a cave... so it curves away from you.

Convex is the opposite.

 

Dude I learned that in elementary school

 

Actually for 87 the Formula and T/A shared the same 16" wheels. The only other Firebird wheels (20 slot variety) were the 15" firebird wheels. The hightech turbo wheels aka Formula wheels came out in 88 on the Formula only and were used till 92 exclusively on the Formula.
