-Stock rear pads
Boiled fluid, wore the rear pads to backing plates and scored the rear rotors and halfway wore the front pads down in one 20 minute session.
Once I switched to HP+ all around, I still had the boiling problem on the same track, but a little farther into the sessions.
When these brakes boil the fluid, you might get a tiny hint of a soft pedal at the first turn, but by the next, they are pretty much gone. Its really sudden and scary when it happens.
I haven't had the problem running Brembo GT calipers up front now and Carbotech XP-12/XP-10 pads with Motul fluid. I think the added mass of the GT caliper helps, but we really do need additional cooling.

I wouldn't consider HP+'s track pads, but that's me. Actually, the mere fact that you were only running HP+ front, and stock rear kinda scares me dude lol.
I fall into this category also. I ran:
MOTUL RBF600 fluid (what DOT fluid was that, that you ran anyway?)
Carbotech XP10 front/XP8 rear
Stock brake lines - didnt touch them.
Nothing else.
I had 0 problems. My brakes felt fantastic all of my sessions. My fluid never boiled. Now, while I'm still fairly newb-ish, I certainly wasn't THAT easy on the brakes.
