5 x 120mm vs. 120.65mm
Anybody running 5 x 120mm rims?
5 x 4 3/4 = 5 x 120.65
.65mm is a pretty small difference especially when you consider that it only moves each stud in .32mm.
I like what I have seen available in this size as the offset is close unlike late model corvette or camaro rims. I am wondering if the size difference is negligible or if there will be centering issues.

Tyler, that was just what I was looking for. Thanks. I had not thought about the lug nut seat differences, so good info. Everytime I think I have an original idea

I've got Beemer BBS wheels under my ride. Centering shouldn't be an issue since the studs are not there to center the wheel. To center the wheel you need the appropriate centering ring (or have one made). This ring lets you center the wheel on the axle.

Indeed. the hubcentric ring is critical. The studs can become stressed and fail, otherwise you should be fine.

That leads to another question: is the center hole the same size as a chevy wheel? Is the hub on a beemer the same size? If they are the same then I should be able to order rings for either wheel and be fine... if not, then I could use some advise.

Hmm, I may have to do some measuring as I had the rear hubs turned down in order to fit the LS1 rotors. It sounds like 74.1mm is the common diameter for the center hole, so...

When you order Beemer BBS rims you get the centerrings with it. The Beemer has bigger diameter hubs and the holes in the BBS wheels are (obviously) even bigger than that. I had mine made. I'm not at home for the coming week so I can't make the measurements for you right now.
Just other the wheels, measure the hole in the wheels, measure the hubs on your ride and have them made. That's the prob. the most pragmatic way of dealing with it.
