The front suspension is composed by the same MacPherson system of the new Palio, but the rear suspension uses a new type of torsion beam.
Pen tilt (fore and aft): A torsion beam joins the pen mounts to maintain correspondence of tilt with respect to the direction away from the user.
The front suspension use the classic independent wheel MacPherson struts while the rear uses a torsion beam with stabilizer bar.
The torsion beam functions both as wheel locating arm and as an anti-roll bar to resist lateral motion of the wheels as the body leans in turns.
Kartsev changed the arrangement of the torsion beams, which was necessary to keep the tank's weight balanced.
Assuming the mass of the torsion beam itself is negligible, the moment of inertia of the balance is just due to the small balls:
Rear suspension was by semi-independent torsion beam for most variants, whilst high-end and 4WD models were fitted with a multi-link independent rear suspension.
The rear axle was a torsion beam with coil springs.
Obviating anti-roll bars, the central torsion beam allows for a limited degree of freedom of each wheel when forced.
He used a horizontal torsion beam with lead balls whose inertia (in relation to the torsion constant) he could tell by timing the beam's oscillation.
