I don't understand why brake dust gets on the out side of the wheel anyway. Looks to me if the wheel designer would consider brake dust in his design the wheel could move clean air toward the brake and the dust to the othe direction instead of the face of the wheel. I haven't seen one wheel on the market that makes any attempt to do this. Looks like a functional wheel that helped cool the brakes would be a good thing??? I don't mean designing a wheel to look like four big noisey fans that would suck up HP but just move a little air.
