I also had green calipers and used PFC pads (08s run a bit hotter than any other pad I used).
I'm not sure how to do the reset on BMWs but if your brakes are only engaging at the end of travel then that would be the first thing I check (brake pressure sensors).

Many thanks! I was surprised how fast the brakes overheated - they were smoking after my first session (which I intentionally took easy). I guess a short track like Summit Point is not ideal for a heavy car like this, but still, one would have expected better brake heat management in a car this carefully engineered...
All best!
