Taking it from the top without answering another threads questions:

The role of shock absorbers.......
Shock absorbers absorb the shocks encountered on a bumpy road, but are not intended to prevent the leaning of a car in a turn.

A shock absorber that is so stiff that it will not compress as a car leans in a turn, is also so stiff that it will not absorb the shocks of a bumpy road.

A shock absorber that is so stiff that it will not compress as a car leans in a turn, will transmit the jolt from bumps in the road to the body of the car.

The role of springs.......
Springs are to support the weight of the car, and are not intended to prevent the leaning of a car in a turn.

A spring that is so stiff/hard that it will not compress as a car leans in a turn, is also so stiff that it will transmit the jolt from bumps in the road
to the body of the car.

The role of anti-sway bars......
Anti sway bars are to keep a car from leaning in the turns.

An anti sway bar is not intended to support the weight of the car.

An anti sway bar is not intended to absorb the jolts/shocks from bumps in the road to the body of a car.-Bob
