i took my e430 summer wheels to the shop to get put on and they said i was missing 2 parts, a lug bolt and this other washer type thing. i asked if they could order the parts for me and they said no because they are aftermarket wheels. I dont know the name of the wheels, but i put some pictures up to see if you can identify them. I've searched all over the internet, and have talked to multiple mercedes techs and none can help/identify the wheel. The two parts on top of the wheel are the ones i need to order, and i would like to get a few more of each in case i loose them again. Any help is greatly appreciated.
