Why all the fuss about those tiny little caps? The lugs and locks are black and you can't really tell unless you're about a foot away. I never understood why BMW even bothered with them in the first place. The purpose of the locks are a deterrent. You would WANT potential criminals to see that you have those locks right from the start and move on. The last thing you want is for a criminal to discover the lock after the 4th or 5th lugs into the crime, now realizing there's more obstacles to overcome; gets pissed off and smashed your windows and scratch up your car.
