I've got the shields on my 300D and it DOES seem to keep the dust off the rims. I disagree with Joe-1. I have had them on for awhile now and my brakes haven't squealed yet. Maybe its quite a number of factors as to whether they will be good or not. I just replaced my front pads today and there wasn't an excessive buildup of dust on the wheel or the brake components.
