So, the good news is that I think I found a better way how to tune suspension. What I did for the Tiger is set torsion bar levers and their physics constraint to a 0,0,0 rotation. As I’ve mentioned before, normally that wouldn’t work correctly, so what I did is set Angular Orientation Target to 0, -15, 0 which means we want to keep torsion bar lever at 15 degrees from default position. With a bit of tweaking for the force of the angular drive (I think last number was very small like 10000) it started to behave really nice - smoothly going over the obstacles with just a bit of the sway on the tank hull.

The bad news is that the way how I setup controls using brakes is not even suppose to work correctly - have no idea why it works in T-26, somehow VehicleRightLeft event is called after VehicleForwardBackward event in T-26, but they are called in reverse order in Tiger. The logic there is a bit stupid, but it works in T-26. In RightLeft event I set Brakes to 1.0 if buttons are pressed, in ForwardBackward I set Brakes to 0.0 if Backward button is not pressed, to disable brakes if you are trying to move forward.
I need to think about how to rewrite this properly.

Can you give me your Constraint Settings for the suspension arm?

I changed the setup like you said with an Angular orientation Target set to 0, -25 , 0 and the stance is good when stationary.

I have the Hull weight set to 46000 Kg, which is roughly the weight of the lower part of the tiger.

Angular Position Strength is set to 4000000
Angular Position Velocity is set to 5000

I cannot find a way to make the suspension softer and increase the angle the wheels can rotate when you go over an obstacle.

I tried lowering both values, and also increasing the Swing 2limit Angle to the of 180 degrees… but the suspension “seems” very stiff or almost absent.

btw… when I add the actual track weight in the TrackSprocketProcessor … the tank will not move foreward backward maybe not enough torque?
The track Weight on one side for the tiger is 2800 Kg, and the Sprocket Weight is estimated at 200Kg
