I am curious is anyone has located anyone selling the "dust protectors" for the smart wheels. I worked on Mercedes Benz for a number of years and this was a VERY popular addition to keep the brake dust from staining the aluminum wheels. I believe, if someone produces these, they could be used on the front to keep the dust of the wheels, like intended and on the rear to cover the brake drum. The rear would be strictly cosmetic. If no one produces these commercially I may have to just make my own, I guess.
