And the big issue with brake dust not cleaned for 2 months is the small particles begin to stick to the wheel paint and can be difficult to remove. You see it all the time with cars that have black dots all over the flat surfaces.
I suppose wheel wax is a must for the F30 MSports. The 403M 19" wheels will hide a bit of the dust since it has gray interior, but they'll still need to be cleaned regularly or will look horrible after a year or so. I'm hoping wheel wax will allow in between cleanings to be simple.
