FFB question for devs, Natual inertia, damping, friction, etc?

I have all these settings on my DD wheel, but I find myself wondering, isnt Beam already calculating friction, the weight and inertia of components etc, making these settings in the wheel software superflous at best? I've played with shutting them completely off and running some and I can't honestly decide what feels more more "correct", mostly because I don't rally or drift old muscle cars like a maniac IRL...

 

I'm not sure if beam simulates friction, but at least I never saw someone turn natural friction off completely on dd wheels because they have less friction than gear/belt wheels
