Request for additional car data.

[vdriftz]

All the physics is in the .car files that you can find under vdrift/data/cars.
You may start by looking at the description of VDrift car parameters here: https://github.com/VDrift/vdrift/blob/ma...ameters.md, but please be aware that some of the data you want are not directly available. For instance, the moment of inertia of the car body is calculated from several "mass particules", including even the driver and her corresponding balancing ballast.
Personally, I would take some of these data as an approximation as best, contrary to the ones that I provided you first, which are based on real-world measurements.
As a aside, in the car I am developing I've put no polar inertia at all, but a single mass particle located (by definition) at the center of mass. This means that the simulation is realistic as long as all wheels have grip, but does not accurately represent what happens as soon as you start drifting. In a way, this makes keeping the car on the racing line a bit easier -- but life is already hard enough, don't you think?

Thanks for the fast response and interesting information.

You mention that the moments of inertia of the vehicle is calculated internally
in vdrift by using various point masses placed in the volume of the vehicle.

If possible please provide these calculated moments of inertia for the vehicle body,
for the wheels, and for any other moving vehicle parts for which calculated moments
of inertia are available - thanks.
