i just got some new z28 rims for my camaro, i decided to see how they look ( i have the rally body colored rims now) and was wondering if anyone knows what there made out of, steel, alumimum alloy? just aluminim? cause there gold and my cars blue need to strip it off but want to do it without jacking the rim up-

 

should be aluminium are they 91-92 z28 wheels or 85-90 Iroc rims or just the 82-84 z28 rims?

 

he said there from an 88 but they look like the 82-84 15x7 style
