It feels a bit unrealistic that wheels use 0 SU, no matter the weight. It would be better if it used SU based on the speed and weight of the ship. The ratio and this feature should be editable in the config.

I think you'd be pretty satisfied by the config setting called enableTrackStress that does the following:

Enable track Kinetic Stress

The default values are likely not balanced for what you intend to use it for, but there is also a configuration option for that called stressMult

Do provide any feedback if you feel these aren't sufficient for you!

Sorry, didn't notice it in my config, ty for responding.
