Vehicle tilts and falls over when turning

[Gen. Hothauser]

I am having this issue with my Lego vehicles and the only fix I could find is to reduce the max speed, which worked well for the Small Car because it doesn't need to go fast.  But, I have vehicles that need to go fast and stay upright.  Any suggestions on how to keep the vehicles upright?

It's related to the mass centre of your vehicle. Generally, the mass centre should be on the same height as your wheels to keep your vehicle stable. You can fix this by moving up your model on the Z axis.

Should I do so such that the origin is coplanar to the wheels, and set the CoM in the script to 0 0 0?

You should probably do the first one and then tweak the CoM in the script if you notice errors in the handling e.g.: wobbling while going forward/backward, shaking while turning etc.

Ok, thanks, that fixed it.
