Ah, thanks for the reminder! I must have blocked that out...
I bled the calipers again, a few times actually. I believe that the brakes were as good as it gets at that point. Sometimes it would still have a long initial pedal, then the second application would be more normal. I believe that was due to the knockback of the pads, and the extra fluid volume it takes to move them vs the stockers (due to the increase in piston area).
Possibly some re-shimming of the calipers to get them more perfectly centered would have helped that, I dunno.
However, on your car, there is no reason it shouldn't feel as good or better than before you messed with it. Air in the line sounds like the most likely culprit.
Also, can you explain your bleed procedure in more detail? Did you open the bleed screw, have your wife pump the pedal twice, then close it? That's sort of how it reads.
Also, FYI, if you went to braided lines, watch the rear line. They don't have an angled exit from the caliper, and thus sit a lot closer to the edge of the rear wheel. Mine would tap-tap-tap on the wheel weight, until I loosely zip-tied it out of the way.
I have to say, on the brakes, I wish I had just stopped after putting on HPS pads. That was more than good enough, and completely headache-free. I am trying to remember that lesson on the V, and resist the urge to upgrade to the 15" 6-pots from the new one...
