I have them on all of my vehicles, including my work trucks/vans. I live in the mountains and am always on the brakes for curves and grades. I bought them first for a 2500 work van that would always shimmy badly and fade at the end of a steep grade. It was amazing the difference it made! Since then, I have put them on all of my vehicles and will surely put them on the ‘18 expo. I have them on my 4Runner, had them on my wife’s ‘16 explorer platinum, 3 work vehicles, etc. I have never noticed any additional dust. I can’t say I have been focused on looking for dust, but I have never noticed any additional.
I can’t say I have noticed dramatically decreased braking distances but they absolutely help reduce fade and warping.
Anyone asking why you would need these on an SUV and that they are not sports cars must not understand physics!! Unless you are tracking a sports car,which most don’t, you are MUCH more likely to experience the negative effects of heat on brakes in a full size SUV vs a small, light, sports car.
