Real and toy tank suspension.

[HERMAN BIX]

Not rightly sure about in real life, but doing it on the lead and last roadwheels certainly does improve the overall performance of the suspension system.

I would make a real life assumption that the increased stresses of the lead wheel being deflected by terrain and the drive system forces, that the relevant system may have an increased pre-load on the suspension method for that wheel.

The Real life Leopard 2 has Torsion bar suspension just like the Tiger 1 and 2, and the Real life Abrams has Torsion bar suspension supplemented by rotary shocks so both of those tanks could easily be tweaked to produce different settings in the individual Torsion bars and it is a job that a workshop could do if adjustment was needed,
The Real life Challenger 2 has a Hydro pneumatic suspension system so it is self adjusting.
I hope that helps.

Just to get you off to sleep here's a little known fact about the Late not much lamented Renault R16 family hatchback,
It was equipped with Torsion bar suspension which meant that the left rear wheel was approximately 70 cms (2 1/2 ins) further back than the right rear wheel.
And if you check a Tiger or an Abrams or a Leo you will find that the road wheels on one side are all further back than the road wheels on the opposite side, the distance being determined by the space between each Torsion Bar.
Because the sprockets and Idlers are not part of the torsion bar system these change an assymetric design into what we perceive to be normal. otherwise the Tank would drive like a crab
