Nowdays car manufacturer put a lot effort in impact safety. This also makes the car stiff at the same time. Ok, they also got softer crusch zones.

For a sportscar, we should look at the torsionally stability number as a "ratio" number, put in relation to the exposed load.

A car that is lighter and has lower CGH might then show a better value than a by number stiffer car.
It must also be put in relation to the total spring stiffness of the car. The stiffer the springs bars and schocks, the greater the torsional load on the chassies.

The picture is a bit complicated, so let us just make the car as stiff as possible.
