If you mean the distance between the two becomes less, then you are correct
... I still haven't plotted the suspension on my Ur-Q yet so I can't tell
you what it does in skewed roll, etc., though.  I'm also not sure whether
the front and rear roll centers behave differently...

It depends upon how you define "roughly" ... what's miniscule to one person
is highly significant to another.
Rather than speculate, I'll demur until after I've measured the car in a few
weeks and plotted the suspension system on the computer ... should be an
interesting exercise!  :^)
