Hey guys/gals....

I was just wondering if there's any type of security measure(s) or tool(s)/device(s) that are available to prevent center cap theft. I ask because last night I went out shopping and when I returned to my car, the guy who was parked next to me was freaking out! When I asked him what had happened he pointed to his rims. Somebody stole his rim's center caps. All of them.

This got me to thinking that somebody could rip mine off. Is there any way of preventing those center caps (perhaps some sort of a third party lock) from being removed?
