FYI: Have had PBR Metal Masters in front and PBR Deluxe in rear. Impressed with stopping ability. Well no squeals or squeaks. Front rims are very lightly coated, I expect them to have that "BMW look" (you know, you wash the car and in a matter of minutes they're black :) )in "maybe" (big maybe) another week. A definate improvement over stock pads. As for the back, they are practically spotless. Either way you look at it, it was well worth it. Henry 89 750iL
