Conversation Between Wheel Experts and msp3304

Peter, I have a 2009 Porsche Cayenne Turbo. I just purchased 22" Victor Equipment matte black Zehn wheels, and want to replace the Victor center caps with Porsche ones. Any idea where I can find them. The Victor caps are 3" in diameter with a 2 3/8 back mouting tab. Thank you in advance, Chris
