The wheel locking nutts that come standard on most cars are abit shite. The best ones ive seen, are the mcguard ones, they have a circular head on them, which makes it harder and stronger steal on the top. so its more difficult to split. but i admit, if someone wants ur wheels , they have got them. (without being to philisophical) thats like that with anything. If someones determined enough, they are more of a deterent.
