if I were to get new wheels what offset would I need?

38mm

38? dang I thought it was 42... shows what I know about it :)

Here soyo... Buy these, then you can just buy 2 more for less than $150 each. Let me know if you want them because I forgot to put a reserve on them so if they go for less than $50.00 I'm gonna take them off e-bay.

Heres what they look like on an rx-7
