I took my Stinger GT1 to the Porsche Club of America track weekend in St Louis.
I'm happy to report the Stinger was always a topic of conversation and embarrassed some very expensive machinery.
I would largely ignore everything up above. If you commute your car and only do a few track days per season, you really only have two things to worry about.
The car was never out of sorts all weekend. There were 8 total sessions at 20 minutes each so if something was going to get sideways, that's enough time to figure out what it is.
After my first session, learning the car (and tracking something this HEAVY) it was hot and not too happy. Tires and brakes, I mean. Everything else was fine.
Also valid: it was dry, sunny and start in the upper 50s in the morning and warming to about 80 in the afternoon.
The Michelin 4s's are fantastic. But they had to be managed, given the weight of the car.
The other thing that was noticable was the OEM brakes had the wobble. Not a warp. Just the pulsating pedal that feels like a warped rotor. It was the crappy brake pads. A few days after my first event, I upgraded to the EPC yellow pads on the front and never felt the wobble again.
Better fluid would certainly be insurance, but I never had fade.
The only "moment" I had was as I got faster, there was a hump exiting Turn 2 and suddenly the car dropped way down on power. I pulled into the pits out of safety. Nothing seemed to be wrong so we went back out. It turned out it was the traction control. I was going fast enough that hump was now a jump. Once we turned off the traction control, never saw it again. Also, the threshold of the TC in Sport mode was so high, that was the first time it reared its head.
No need to "mod" this car.for the track. It's built that way.
