C'mon salvo. If someone wants your wheels bad enough, they will have all the keys to all wheel locks. The wheel locks, like any theft deterrent is just that a deterrent. So the wheel locks are there.....the thief may move on to the next one without wheel locks.
Actualy, stealing the BMW is much harder than just stealing the wheels. With coded driveaway protection it is virtually impossible to start without the key. You would have to tow it away, and most car theives do not use tow trucks, it would be too easy to get caught with that MO.
So....the harder you make it to steal just the wheels the better off you are.......
Adding the tilt sesor equipped alarm is also a great deterrent, when combined with the wheel locks, it really slows the theif down.
Remember the last thing the theif wants is it to take time, because time increases the chance of confrontation, which is their worst nightmare.
I guess that's the point.
