Yeah. I am thinking having the very stiff ride to keep the car low for optimum ground effect. But have more compliance to cater to kerb riding. A kind of compromise.
The logical kinematics, to me, say that this could be solved with a progressive Belleville washer stack in place of packers, or somehow harnessing the roll-bar (not used in heave) as a helper spring at high loads (preload on ARB would help maybe? Or add a stop-twist lug in the center of the bar that can only move a certain amount before binding in heave).
I would speculate that if those options cannot solve it, the real issue would be the rear tyre sidewalls are collapsing under the load, and I'm not sure how Pirelli could solve that outside of adding run-flat sidewalls to the new 18in tyres.
