Just some speculation...
I think that also plays a factor into it, I didn't measure temps of the tires, but I did check pressure. When cold, all four tires were set to 33 psi. After about 6 laps, I checked and the left side front and rear were about 42 psi, and the right front and rear were 38 psi. That told me that the track is much more abusive of the left side of the car, and while I didn't monitor temps, the left side is getting much hotter than the right side. I dropped the hot pressure down to 37psi on all four and went back out. The definitely felt more stable after that. It's something I've got to keep a closer eye on for sure. The spring rates also attribute to the looseness, being 9kg front and 7kg rear. Coming from years of drifting though, I like it loose (eerr, cars that is!) haha.
