Take it from me, the rack was forced upwards by the excessive downward droop of the inner wheel . There is no force ( other than minimal ) on the rack from suspension movement until such time as the track rod necks on its housing, and with dampers of the correct length that should never happen in either direction of suspension movement

Ok, but the track rod attached to the wheel on the inside of any curve is going to be pushing the rack upwards all the time. I don't see how, when the track rod reaches the lower end of its travel (i.e. necking on the inner ball joint) that is going to push the entire rack any further upwards.
As an experiment, you could re-create this scenario by unbolting the rack and lifting it by hand until the inner ball joint bottoms out (necks), whilst simultaneously pushing the rack towards the wheel on that side. What will happen is that the rack will try to BEND DOWNWARDS on the affected side, while LIFTING UP on the OPPOSITE side, since the rack and the relevant track rod now form a semi-rigid structure.
Or is that what you meant and I just mis-understood you?
