Anyone know how to keep my new wheel vintique chevy rally caps from exiting the vehicle at normal highway speeds. I installed new wheel vintique 15x7 rally wheels with corresponding beauty rings and center caps. Twice, I have spun off the center caps from each rear wheel and at 57 bucks a pop it's beginning to p##s me off. Wheel vintiques was little help when i called them. The caps seem to pop on very snugly. Has anyone else experienced this problem? Is this yet another example of inferior chinese crap? Thanks for help
