Found the same pictures. I would guess that it works similarly to Tatra but not sure. However, it can be easily computed if we know the track and camber values of an empty and a loaded car.

I'd like to make it handle reasonably well while maintaining the difference between the two suspension types, but I don't know how to approach it. If you want I can send you the share zip file and you can play around with it and I can then add you as a collaborator 
Here is a video of Škoda 100 (which has almost the same suspension) and it does a very similar thing: https://www.youtube.com/watch?v=fd-WWpRdV8c. I have the same problem with the Hanzmund mod and found two solutions to decrease the lifting a little. Firstly the suspension can be made stiffer and secondly the tires can be over-pressured to produce less grip. The tires in LFS have much more grip then the historical ones, which increases the lift as the outer wheel tries to get under the car during cornering.
If you like, I am opened to cooperation, but must admit, that I have never driven these IRL. However, I will try to contact one happy owner, who has Škodas with both swing and trailing axles. Heard he likes to talk about his cars a lot, so will ask him about handling on the limit (if he dared to try
). If I will get some useful information, will post it here.
It would be nice if you could get some feedback from someone who has driven these IRL
