Thanks, I think I'll be getting the Sprints then. I was seriously thinking about the Intrax springs but I have seen an 2000 Altima with Sprint springs that looked great. Right now I have 16" rims but I'm looking to upgrade to 17s. Everyone seems to be suggesting the 18 or even 19" sizes but the Altima I seen with the Sprint springs had 18s and they were rubbing on the inside fender in the rear. They had to roll their fenders back and I don't want to go through that.
