I have about 5000 miles on a set, both front and rear, on my 04' ABS with no problems. I did notice a whirring sound from the fronts under semi-hard braking, but it seems to have stopped, and I think this was just "bedding in" noise. My rotors look fine and braking power is as good as the stock pads, and you can't beat the price!! Try a set.
Timely, just about to stick a set in the front of mine that came free with the Z6 tyres I bought. All the new pads I've put in made the whirring noise, I quite like it!
