Well I'm not much of a rim/wheel guy, I don't mind the stock look. Except, I found an incredible deal on a set of rims. These are the ones being sold: 18 aftermarket rims The catch is, I've convinced the seller to trade some of my old gaming equipment for the set of rims. The downside being, I can't tell very much about the rims from the post, and I'm unsure of if they will be compatible w/ my 100% stock 1999 GP. Obviously from what I've read, 18" seems to be standard. I'm just not familiar w/ the other aspects of finding a wheel that fits properly.
