Recommended by the guys at Bimmerfest.com. I installed them on a 2009 BMW 650i (20,000 miles), braking is much softer than the factory pads but stopping distance is noticeably shorter. I didn't measure exactly, it's more of a perception. The brake dust is interesting, it is much finer than the OEM and much smaller. At the OEM, after a week of daily driving on the road, you can see a huge amount of brake dust on the wheels. With them you could go about 3-4 weeks before receiving the same amount.
