Dose any one know were I can get a good set of brake dust shields for my frond brakes to try and keep them clean from the brake dust

 

Most "experts" don't recommend them as they make the brakes run hotter and potentially warp the rotors. Does your car have the lower dust pads? I would have thought that it would have come with them. Complain to Lexus about the dust and see what they will do. My wife's 2007 IS had the regular pads and Lexus changed them to the lower dust at about 500 miles. I don't have any accumulation of dust, regardless of time in between washings.

 

another option is to wax your wheels to help keep your wheels cleaner
