I have installed these pads in combination with StopTech slotted and slotted rotors on my 2005 BMW and so far after about 1000 miles they are working as expected. Considering the time of year (winter) I haven't abused them much but they are quiet, quite dusty compared to other pads I've used and offer solid braking. I will know more about their overall performance later this year as it gets warmer and my riding style becomes more aggressive. So far very happy with the product.
