Where can I get this??

I wanna find the Audi rings for the back of my car but in black, where can I get them or is it a diy

you just paint them black

I have seen them on ebay a few times,

get a second set....... scuff sand them and paint them black, then when you decide you don't want the black rings anymore or sell the car, you have a chrome set to put back on
 
you can get them on ebay as cheap as like 10  bucks, but out of cuba or somewhere like that, my dealer has them for 27 bucks

Here ya go, I'd use your current rings as the black ones and use these brand new ones as your crome set.
