Gents, it was my second day on those pads, with something like 500km easy street driving in between.
The pads visually had at least 8-9mm at the start of the day.
By the afternoon my tires heated up properly (r888r) and I also dialed in the pressure right, so the grip was really good. I started hitting good lap times consistently, eventually breaking my personal best.
At the end of the second very fast session the pedal suddenly got soft and there was hardly any friction in the pads. I was lucky it happened in a safe place. I cooled down and went into the pits only to find my backing plates squeezed against the rotors. With zero pad material in between.

I am running Pure turbos, so it might be just too much power on a heavy car for those brakes. Without proper cooling even the RSL29s could not keep up.
If I need to buy a new set of pads for every track day this becomes a prohibitively expensive car to track.
