I've never liked OEM wheel locks because they are pretty easy to strip, plus there aren't very many different lock patterns for that type of lock. A good thief can easily carry a set of keys. I've also seen thieves use a regular socket that is one size too small to get locks off - you hammer the socket on over the stock lock and twist as if it were a normal nut and off you go. That being said, if you already have OEM locks, I probably wouldn't replace them. I started the thread because I didn't buy the OEM locks and am looking for a good aftermarket set. I have used McGard as well as Gorilla locks before and have liked them, but I wasn't sure if they are car-specific. If they are, I wanted to know if an application for the 3 had been created yet.bobmtb said:Any difference between McGuard and OEM Mazda lock bolts? Worth the cost in changing?
