All pads have different characteristics for initial bite, pedal feel, and so on. It isn't about whether they are dustless or not, it is just that OEM are being compared to others, which usually have less dust. Making dust does not equal better performance, as the carbon black is not added for performance reasons. If you don't like the performance of the pads you have, try another pad formulation.

My Axxis Deluxe pads on several BMW vehicles, properly bedded in, had no reduction in performance over the stock pads. However, every pad will be different.
