Overall they are a great tire. My next tire will be the Pilot Sport cup 2's, also in 285/35R20 square setup.
All in all, if I were going to do just track work extensively, I'd stick with the R888's, but I have about six events per year. Unless the Pilot Sport Cup's outperform the R888's on overheating I will probably go back to the stock tire. Despite having A LOT of rollover and giving up a fair amount of grip, they are very controllable and pretty fast.
I did change to SRF. The pedal still faded some, but I think we have "brake fade compensation". I felt the car correct some of the pedal height while braking. The front pads last six full track days without making the wear sensors. I have now worn OUT, two full sets of rear pads. On my third set, I turned off DSC to conserve pads. The car is pretty good without DSC, and not as hard to control as I thought it might be.
The biggest surprise was probably to the Porsche cayman's. I think they were surprised that I was able to not only keep up but pass. Especially in the turns. But I was in some really fast groups.

Interesting about rear pads as fronts usually take bigger hit with heavy front engined car. Nice to hear rotors holding up though ... assume steels on yours, this is what I opted for too. Curious did you get the BMW maintenance package and does it cover pads and rotors? Appreciate all your info, as these cars deserve a healthy dose of track days. My M5C on order so just planning ahead ...
BTW, VIR long back straight should have had you passing more than just Caymans. I enjoy surprising lots 911s and Caymans including GTS and 4, with M3 CP so hoping M5C will be same or better. Especially our tracks with longer straights like Daytona and Sebring where 600+ hp comes in handy.
