Thank you for your pointers.
When driving on a normal closed circuit, is the ground contact always calculated using the mesh of the terrain directly? Or is this only used as fallback when leaving the race track?
I did a checkout of your sim branch. Unfortunately I wasn't able to compile it, receiving the following error:
Code:

Compiling the latest version from the master branch was successful. One thing I noticed however is that the cars react very nervous (I'm using mouse steering). It is almost impossible to drive in a straight line, even at low speeds.
Another thing which I could observe was a very weird collision behaviour with corner curbs. Sometimes after hitting a corner curb the car was flung over almost the entire map.
