It's funny because BBK's are bought many times due to their easier pad changes, but with my 28mm PFC11 compound pads I literally swap after 30-40 track days. I don't swap them out for the street either as this compound is somehow quiet.
The data-driven approach you have is fantastic. I hope you get to the bottom of the DCT issues you're having. It's annoying you keep running into a wall there. Maybe a baffled pan would help?

I have always heard good things about PFC brake kits. I've never driven one.
I started down the path of AP Racing 6 years ago because I had an opportunity to get a used kit. At that moment, the Stillen AP kit was by far the best bang for the buck BBK I could afford. And the "used" kit was actually not really used----the fronts were entirely new--replaced by AP for the original owner, and the rears were completely refurbished by AP in England. So, the kit was in incredibly good shape for the price. That Stillen kit always treated me well. It was the most reliable mod on the car. I'm going to keep it and put it on my street E92 M3.
hehe 28mm pad on the PFC....super beefy!! I just installed the 25mm pads into the front calipers of my Essex AP kit today. I hope that they last a decent amount of time.
Check this ridiculousness out: It looks like I stuck a thick-cut piece of banana bread in my caliper!!!!
As far DCT issues, yeah.....it's a bummer....but in fairness to the car, I am pushing it beyond what BMW intended, and stuff like the transmission is completely stock, which is pretty impressive when you consider the fact that all the track days on this car have been done with a supercharger on there. I give BMW a lot of credit for making a car that has held up so well to all of this nonsense. Hopefully, I'll be able to drive the car later this week and see if our first round of maintenance helped the situation.
Regarding a baffled pan, I have also been wondering about that. As I have been reflecting back on this topic, I'm seeming to realize that most of the shifting issues happen after left turns/bends. It's not 100% of the time, but it's probably more than 90%. I've started asking where the suction from the pan occurs, wondering if it's on the left side of the pan and maybe as the fluid sloshes to the right that the system is starving, but I've been told the suction point is in the middle.....dang...I haven't given up on this line of thinking yet though....As I mentioned, we overfilled the system, so we'll see. I talked to SSP Performance last week. Nice guys. We had a good conversation.
