I shared this in a FB group, but wanted to get some feedback here.
I have read the posts and articles, so I understand the mode settings. Please, no lectures.

2018 SS 1LE. DTC-60s all the way around with SRF fluid. Factory SC tires.
Stock power/suspension except for a recent flex fuel tune from Jannetty. I'm advanced/instructor level, but I have been running a FWD platform for a few years. My first time out in the 1LE in June, I spun it in RACE mode, so I decided to back it down to Sport 1 for the last few track days while I got a grip on how to manipulate the car in the corners better.

On Friday, it was my first time out with the new tune, and my speed was already picking up from driver improvement. My first session out in Sport 1, I could feel the ESC kicking in badly through the esses -- so much so that I wondered whether there was something wrong with the tune. Nonetheless, I continued on, knowing I was looking to go to Sport 2 at some point that day anyway.

Well, 15 minutes into that first session, the brake pedal went soft. Came into the paddock to find the fronts smoking, and the calipers had turned a dark maroon color. After cooldown, the pedal came back and I went out the next session in Sport 2 with no problems.

At lunch, I flushed the fluid, but all I had was Motul 600. The rest of the day, I did Sport 2 with zero issues, even with longer run sessions and higher ambient temps. The paint color continued to darken some, but I suspect that train had left the track with that first overheat, and it's now going to continue to darken with "normal" heat levels.

I've never been nice on pads, but this is the first time I've had this happen. The going theory is that the ESC put me over the edge, and I'm fine now.

Just want to be sure I don't need to do anything with the calipers. Anyone else have their calipers change color? I've had several people tell me it was always going to happen at some point, while other Camaro owners experience nothing like this after years of track use.
