Can't get F10 racecar to go fast, flips at higher acceleration

[silverjoda]

Hello,

I'm trying to get the f10_racecar.py script from pybullet robots to work with a larger velocity. (i've removed the second car, and the lidar and all the other stuff around it).
I just can't get the damn car to go faster. If I increase the velocity of the diff ring (joint 8) to 150 and force to greater than 30 then the car keeps flipping over, as if there is wind pushing it up. What is going on? It seems as if there is some damping or limit on the body of the car itself which prevents it going faster than roughly 2m/s.

Any advice?
Thanks in advance,

Teymur
