If they fit closely around the lip on the hub and have a lip for the rim center that also fits closely, I wouldn't be worried about it at all. Or, if they come with hubcentric rings. I have personally never had any problems with using wheel spacers, even at the track. And a few of mine didn't fit closely around my hub's lip. I also very rarely have rims that the centers fit closely around the hub's lip, even on my track cars and I have never snapped studs off. (Basically the same principle.) But, then again my car barely weighs 2000lbs. Another option would be ARP lug studs if you just want that extra assurance. It makes sense that extra stress is placed on the lugs when the center of the rim doesn't fit closely to the hub lip, but it's harder to say what force would cause them to snap off. This is kinda like the heated vs. cut springs debate. Even though one side is scientifically proven to be better, it will still be debated for eternity. I say just buy a set of hub rings to go with them, they are probably less than 20 bucks anyways, and you will probably be ok.
