HPS, however, are probably one of the worst pad I've ever driven on, a close second to the $16 set of Duralast pads. They have no bite, have no tolerance to heat, and give you no feedback through the pedal (just mush). I had HPS installed when I first went turbo back in 2006. I had a panic stop at around 80mph and they simply glazed over instead of slowing the car (stock 1.6L brakes) and I almost wasn't able to stop in time--I replaced them immediately.
If it wasn't for the dust/squeal* they'd be great street pads. The dust/squeal suggests they are working hard and have a high cf. I believe it's in the .50-.55 range.
They make a great autox pad and track pad for stock power levels.
*They don't always squeal, if you use grease/anti-squeal when installing you can usually reduce the vibrations so they are quiet. I've run 2-3 sets of them, but ultimately started running ULTs as they are ceramic, have just as good of a pedal feel, bite, tolerance, etc, but dont dust quite as much and don't require effort to stop from squealing.

I always thought they were very easy to modulate (street/autox/track) and have enough friction that if you press harder, the car will flip head over heel because of the shitty rear bias.
I can't stand a pedal with any give--might as well just introduce air into your lines.

Brain, thats why I put your old HP+s in the back on my car I wont notice the pedal ****, and they should be paired decently with the parts store ceramics.

Play nice, kids.
Yes, HP+ dust and can squeal if not properly bedded. But they do have a higher friction coefficient and higher heat range than stock. So everybody is correct.
For reference, I bought the 11.75 Dynalite setup from V8Roadsters (local to me) and they came stock with the BP-10 pads. Shandelle advised me to run them for my track weekend at Sebring and then we would figure out which compound to go with next. I was metal to metal in four sessions. That last 1/2 of the pad vaporized in very short order. Vaporized.
Prior to this I was running the Hawk Blues and way back also ran the HP+ when I was much slower. Most recently I had tried the Cobalt XR2 with the stock calipers and LOVED THEM. They stopped hot or cold, required no bedding, and gave me much better feel than the Hawk Blues on the same calipers and rotors. I currently have some XR2 pads on order for the Dynallites and I have ordered some Performance Friction "01" compound pads (not the "10" compound discussed here) to try from OG Racing (supporting our sponsors). I'm hoping to like them and will report back once I have given them a whirl.

On my TSE 11.75'', HP+ dust like mad but aren't noisy. They're good for auto-x, bad modulation on race track so I have no confidence and brake too early each time... went back to Carbotech XP12 and they're awesome on the track with really great communication and modulation. Too much bite for auto-x tho....

I think I am going to give the HP+ pads a try on fresh rotors to make sure there are no issues with previous transfer layers that might cause noise. Worst case I will sell some 95% HP+ pads in a few weeks if they suck on the street.
