Used 18" M3 wheels are often for sale at low prices. You will not be able to use these on your 323. Only the fronts as mentioned. Also the shawdow chrome finished if scratched can't be refinished so those will be shot. I'd suggest getting replicas in the correct offset and new if you really are set to get them. Or have another set of fronts available and only buy the fronts from this seller. BTW..they're going to move this thread to WT once admin see's it.
