Re: How does torsion-level keep the car level on braking and acceleration?

The essence of TL is that it gives the effect of suspending the car at its center of gravity--or at least near it. That is the goal of all interconnected suspensions from a Citroen 2CV to an Austin "landcrab". That way a bump results in upward translation of the whole vehicle rather than rotation about the CG. Thus the disturbance is far less.

Naturally small changes in load move the CG thus the leveler is necessary.

To your question, the rear torque arms pull the back of the car somewhat downward during braking and thrust it upward during acceleration. That helps counteract the CG being above the road surface.

A TL car in good fettle will actually rise slightly on brisk acceleration.
