I ran them for many years but it was not a pleasant ride. A 1" thick plate with locking nuts in recessed holes that require a very thin walled socket to remove. Then screw in studs in the 5 bolt pattern. I am convinced that the "spacing outward" of the wheels makes for more than normal road wander. Also, when removing wheels, the studs will back out so you must be attentive to make sure they are screwed back in before installing lugnuts or they will come loose! From the voice of personal experience, you won't like them.
