the system is very good every nut is a locking nutOne of the most secure wheel locks are made by Gorilla. They have spinning sleeves, which makes it virtually impossible to remove them without the key. I have them on my 2009 SRT to protect my expensive forged Alcoa wheels.
Also, for maximum security, I would install two per wheel (opposite each other). Thieves actually prefer a single wheel lock per wheel- one less nut to remove. They simply raise your car and then spin the tire until the wheel lock is on top. Then they drop the car and the bolt breaks off. This doesn't work with two wheel locks (see photo).
