Mate, the car weighs 1450kg.

Half on the front, half on the rear.

This rough calculation leaves you with 360kg or so per corner. Imagine the g force in or the bumps - if these springs are 4kg/mm the car would hit the bump stops coming out of the driveaway hehehe.

I'm actually even surprised that these springs are still so low - 8kg/mm is comparable to a sportsbike springs - and the car weighs much much more.

If you want to fight body-roll get stiffer anti-roll bar. Do not fight the roll with stiffer suspension units, they will just make the ride harsh and skip over bumps in corners.
