I want to be with you and understand you but i still disagree..Nothing to do with geometry or springs - this is a shock absorber issue. Autocar first reported the issue as the shock absorbers not capable of damping the suspension movement sufficiently. Insufficient damping on bumps etc leads to the suspension quickly reaching a position where the car is on the bump-stops. It's obviously worse with the car fully loaded since the suspension is already compressed and the distance to the bump-stops significantly reduced. The upgrade involves fitting new dampers and bump-stops. Even though the damping action is increased - the normal ride doesn't seem to have been adversely affected.
The car's production spring 19 so i expect the old suspension issues are past and thus having upgraded parts.
It's not at all any matter of shocks and they do not reach bump-stops.
Not still fully loaded car yet..
when pasasing over anomalies of 2-3 cm's still car in the back jumps!
