Thereafter, for some reason after getting the corner balance done, my car ended being way lowered than expected and my caster is now at 8.7 versus the recommended 7.8 caster and the car definitely does not handle as well as before (the crispiness on the steering feel is gone). 
Now I am trying to decide on raising the car again (a bit) or getting the Tarett (or Elephant) LCA adjustable center pucks to reduce the caster from 8.7 to 7.8.
You are 100% correct stating that changing one part affects the function of the other components
I do not have the GT3 LCA's, but the car has the KW-V3's, Tarett GT3 sway bars with drop and toe links (with bump steer F&R), but again everything has to be matched to work together... live and learn :-)

This is good stuff, right here.
So this demonstrates that the pivot of the LCA is not as "perpendicular" as it appears.
Now im not sure that relatively minor change in caster is important (I was much further out of spec all of last season). But it's good to understand that relationship.
Coincidentally, I was just on the phone with another forum member who helped a friend install H&R lowering springs, and as I suspected in my post below, they do indeed need adjustable toe links. (And unlike caster, toe really needs to be "right there")
Thanks for the info, gilles!
