Yes, the spacers are a one-piece unit. They have holes for the existing studs that you thread nuts on. They have new built-in studs that you put your wheel on using your normal wheel lugs.

They should not break. You shouldn't have to adjust camber for them. They make the Z look better. 20-25mm on an '06 will bring the wheels out flush, like they should have been from the factory.
