I'm not really hopeful on finding inertia for almost any car. Any tips as to what to exactly try and enter as search? Or as there are databases be it on webs or forums for dynographs or very limited aero info is there one for vehicle inertias? Really not finding anything in the inertia department.

No idea how someone magically gains information about inertia from footage. From telemetry, sure maybe something can be gleaned.

Even if one finds or calculates the inertia what's the point if explicit inertia is buggy and not to be used? Or what's the conversion to the "KS box" inertia?

NHTSA posted inertia values for a bunch of cars.

You can ballpark it fairly well if you find a step input and do correlation; of course, the rest of the car has to be very accurate. If you have far too much or too little yaw inertia in, it's obvious when you look at it, the difference won't be small. The other axis can be difficult, but that's why you should have ballpark values to use as a guide. Sometimes OEMs post them too, like when Mazda (?) posted yaw inertia (and CGH) for MX5, FD3S and RX8 in some article.

I = (1/12) * MASS * (DIMENSION A^2 + DIMENSION B^2)

Input kilograms and meters and you get kg-m^2.

Are there any plans to continue updating the pipeline document? Would love to learn more about the new cphys features

I have some corrections to make and some small additions to the existing tools, but Cphys support is not planned currently.

The best place right now is mod-talk in the CSP Discord. Ask directly. Cphys is kind of chaotic right now and subject to change so it'd be better to fully document it all once it's "done". Who knows when that is.
