I have found that somewhat true as well.  But beyond a certain point (which 
comes up fairly quickly), the addition of front stiffening is key to neutral

First rule of quattros:  Quattros understeer.   You have a baseline weight 
problem, not a spring problem wrt that primary rule.  I put c/o front in my 
5ktq 5+ years ago, and have done a few in the S car chassis since, and found 
that the rears slightly stiffer than the fronts gave the best of the U 
character.  Rake angle front to back is also key to getting this all right.

The 92 was the stiffest stocker, and brought 'stiff' comments from the target 
buyer.  Hence, in 93 the springs went softer, and the rear bar deleted.  I 
find 'wishy washy ride' to be more a shock issue, not necessarily a spring 
issue.  I also have btdt on bigger front antiroll bars in 44chassis cars, and 
firmly believe that the 'swaybar method' is quite effective in front, but not 
back.  The inherent design in the multilink rear suspensions in the 44chassis 
cars negates the need for rear antirollbars
