All you need is the wheel, whomever you get it form. I have not seen them already done. I bought mine online, when the wheel arrived I sent it out to be chromed. Now that is the secret, you got to make sure the place that is doing it is good. You already will have an aluminum wheel that needs to be chromed, it is tricky so I hear. Do you homework in your area of a good chrome plating shop.
If you do find it already plated, let me know where. It will be a good source.
