I've had quite a few sets of aftermarket wheels over the years and not one problem. in fact, I can only recall a minute number of posts regarding out-of-round wheels that were immediately replaced. As far as looks go, the sky is the limit. Regarding oem, check eBay for take offs and replicas. I've also owned 2 sets of GM replica wheels and they're every bit as good as oem. The bottom line is get what you like and don't give it a second thought. You have absolutely nothing to be concerned about.
