How wide are the wheels? Voodoo motorsport are re-drilling wheels but they aint cheap. But if your wanting it done, I wouldnt be trying to cut any orners. If done properly they should be safe, but I'd try and see if adaptors will work first. I was thinking about getting my wheels redrilled to 5x100 from 5x120. Get the holes welded up and new stud pattern drilled, but its cheaper tp buy BMW adaptors (and they aint cheap). BUt if I got the re-drilled, it meant the wheels could go stupid wide.
