Ricks had a thin round metal disc that bolts to the inside of the cap using existing screws, then a thin cable runs to one of the lugnuts and if the cap comes off, it stays with the car BUT some have said "what if that cap slams around at 60mph until you stop...any damage to the body and wheel opening from it?? "
