wtf is the black ring that like 2mm thick and the thin metal that shaped like a open circle? i have 4 of each..

 

Centering rings? It's on the inside of the wheel, correct?

Yup, it's hubcentric rings that goes in the center bore of the MM Evo 5 rims before you install it on your car.

 

so um what the thin metal silver thing ?

 

Do you have pics of them?

 

They hold the hold the rings in. From the back of the rim, you put the centering rings in (the thick piece), then you'll see a little groove. The thin wire piece goes in the groove to stop the ring from falling out when you take your tires off.
