We have a small track (test track) here in Switzerland.
New road surface and super grip Level
The yellow arrow shows the direction of travel
The red arrow indicates the point at which the "Z" starts to stutter (starvation)
(Full acceleration after the very long left curve (approximately 0.8 G-Force) and just before the braking point)
This happened to me even at half full tank
With a full tank no problem
I hope I could describe it properly
Greetings
