McGard locking lugs suck! I had the ones with the different designs over on the head of them. 5 different sets, "required" 5 different keys to get one of my rims off because I was paranoid.
After 3 months of
FL summer... I go to swap my stock rims back on about 2 hours before I need to get to the airport. What happens?! The heads of the crappy locking lugs are just snapping off and I can see rust on 'em. I pounded a 12-point socket on them and still got them off, except one which I had to cut off, it was a bitch.
I switched to some different brand with the spleens that the key slides over and never had a problem.
