Just like the title says, I am looking for the stock rim size so that I can buy some rims that look better than the stock ones I currently have.
I tried google and could not find the size spec I thought I saw 15x8 on a thread but no I can not find it.

Thank you for the help.

 

I found my own answer. 15", 7" wide, +50 mm offset.
Now to find some rims for the ZR2.

 

The offset can also be described a 6 inches of backspacing.

 

A great set I use for my ZR2 are the American Racing 172 Baja's, They like 90-100'ish a piece, I love them and they got a -6mm offset so the tires line up with the ZR2 fenderflares perfectly. Bought mine off Newegg but amazon and the such have them too.

Already been answered, but they should be 15x7, 6" backspacing
