What's that called when you buy a 3 piece rim and you get the inner piece to be BLACK (i guess to match the black paint of black cars) and polish the lip, it looks pretty tight... i want to find out more about it though, i've seen it on some audis

 

Black chrome with a polished lip?

 

black chrome? no.

 

that center goes by many different names. some people call it onyx, gunmetal, anthracite, burning black, black chrome.

 

guess so then =P
