I can buy a great set of aftermarket rims the Bolt Pattern is 5x114.3 and our Intrigue has the standard GM 5x115 Bolt pattern. Will the .7 of a mil. make that much of a difference or can I just bolt on the suckers. Any-one do it?

Its been done before, but it can cause some problems, a lot of people notice more vibration with that bolt pattern, and lugnuts being sheered off is not unheard of. Instead of being distributed evenly between 5 lug nuts, the force is more like on 1 or 2 of them.

But they will fit, some folks have had no problems, some folks have had some doozies.
