Sadly, I live in one of the worst places in North America for theft of auto, and anything attached to that auto. I'm looking for recommendations as to high quality wheel lock nuts (not sure of the name but they are the lug nuts that are "keyed" and you need a special socket to take them off.) Only problem is that when I go to local vendors and say I want 5, they look at me as if I'm insane. I just came into a set of 5 wheels / tires which I'd like to do my best to keep. Can anyone point me in the right direction?
