The number of shims depends on what the camber needs to be for the wheel to be aligned from top to bottom. A good guess is three shims per stud. Then you just let the alignment shop correct it. If you try to eyeball it you *might* come close, but when I did I didn't even get into the ballpark on the passenger wheel.
