Hey everyone, I’ve been reading up on the rim threads as much as possible. I would have thought buying rims for a vehicle would be easy and simple, but I find myself confused. What exactly does the rim offset mean? I’m in the market for a 2002 C5. I’ve read that many owners have upgraded to C6 rims, does this mean you now have a 18” front and 19” rear? Or did they buy same size rim diameter as a stock C5. I’m currently looking at some C6 Z06 spyder from corvette depot.ca, but like I said I’m confused!!
