Chuck the Tire Man told me about a method to stop wheel covers from rotating.
I believe he said Lazy Daze adds a 1" long threaded nut to one of the wheel bolts. The original wheel nut is left in place. The extended nut is added. That extended nut fits inside the fake nut on the wheel simulator. The wheel simulator will then only rotate until it hits the nut extension.
Sounds like a good idea to me.
