I did some testing on a TC with an accelerometer installed and the peak lateral g I saw was 2.2g. I'm sure there is more in it than that but that's as fast as I could get. Offroad would certainly be lower, I would guess around 1.5g.

If the lateral g number is to high you will see the chassis bottoming out in the Dynamic simulation.

My recommendation would be 2-2.5g for on-road and 1-1.5g for offroad.
