Based on what I'm reading here it looks like Stoptechs for me when I redo the brakes this spring (too cold to work in the garage right now). Given my driving (all highway) I hope they last as long as the stockers (88K miles at the moment). The selling point for me is cold bite.
Just wish that Axxis sold Ultimates for these calipers. Had those on the '07 WRX and absolutely adored them.
