Indeed, there were many red flags and I was almost the person who go out the pit lane and enter the gravel. It's the first lap after the lunch brake and the tyre temp drop back to single figure. I've reduced the corner speed by a third but still slide at the first corner and almost got into the gravel. My car is on the Michelin PSS tyre. When it's at 30-40 degree, I found it's really hard to lose grip. But at single digit temperature, I found it really has almost no grip.
Yes, I plan to do more in the G29 (less likely to be more than 5 days per year). I don't have a specific track car and the other car I have is a 520d touring which I think is less suitable than the G29. The car come with the blue msport brake which is sourced from brembo. I found them okay. But during the day when the brake got hot (I mean disc turning blue hot), there were some vibration when braking. I think it's caused by glazing. You are more experienced in track day so if you think differently, maybe give me some suggestion on this. Fade-wise, not much.
