The wheels I have Came with 2 4x100 sets of holes. Each set for different style lug nuts. But since I ordered mine 4x114.3 and only needed the hole for the "conical"lugs it only came with 4 holes. So I think the wheel it self is strong enough for 8 holes since they make them with 8.
So if anyone knows of a shop that read drills please let me get their phone number
