This is the first Lexus I've owned and one of my first observations on my F was the very dusty brake pads. I got the 20 spoke hand-polished wheels, very nice, but within a week they are pretty well coated, not to mention the calipers. So after some research I ordered Carbotech aftermarket pads and swapped them out. I've had those on about a week now so too soon to be sure. What have others done on this issue? There really didn't seem to be many options at all as far as aftermarket pads go.
