Not sure, but I believe Dub Caps are locked down under your lug nuts
Spinner caps on the other hand..... I saw an old chrysler minivan that had them and they were vibrating so hard that i was afraid that the fuckers were going to fall off and hit my 5 , so I don't think they're as secure
the hubbies kill me...........there is this girl that has them on her cavalier with the domino's pizza sign on her roof..........goes to show domino's don't pay s***.
