My M3W came stock with this hub. I highly recommend getting one for your car. As they say "no wheel, no steal."
I like the security aspect of this, but then the question is, when you take it off while out in public, what do you do with it? Afix a shoulder strap and sling it over your shoulder? Or just pretend you are driving while walking down the road?☺
But seriusly, where do you put it?
