I've had these on the front of my smart for about a year and they do keep the dust off but I didn't notice any mpg change. I just put on some ceramic pads from O'Rielly's about a month ago and there is NO dust on the fronts now.So what do I do? I just got finished making and installing some disks to cover all 4 of the alloy wheels for better aerodynamics so the dust would be hidden anyway. Chumly
