Thanks Eclipse Motors and isugoo...
My experience with the HPS was the opposite of isugoo in the M3. I used to have HPS pads in my 2007 MKV GTI and they completely fixed the squishy brake pedal in the GTI with a firm and right-now feel. They were low dust as well... they were really excellent pads.
I think that I'm going to try again the HPS pads for the front and then the Axxis Deluxe in the rear in my M3 just because I would like to continue autocrossing and ceramic pads all around is not going to cut it for those occasions. Some braided lines will be good also...
