Steel wheel, SBP

I cant say yes it will be a problem. Yes you could probably have a special spacer made to fill the voids. I wouldn't run them. They look like they were designed for some other application, something with disc brake hubs maybe ?

The Magnum 500 wheel is a good example here. These wheels dont have the 2 continuous rings as seen in your pics. Instead each lug hole is in a stamped finger like area. The whole world knows about wollered out lug holes in them.
