Center Caps?

I just bought some Tenzo Passion Rims and I need to buy a few center caps for them, I have looked online and have not really found what I am looking for, anyone know of a site that specializes or has a good selection of center caps?

Are they classified a racing rim? If so then they usually don't have center caps, because they have to be removed anyway if you track your car.

I don't know about that, all I know is that one of the rims is missing a center cap and I need to buy some new ones

Try the site for Tenzo or whereever you got your rims from.
