this is the precise effect i am interested in, since it gives better turn-in
and then steady state is tuned with bars and springs. >>
My understanding is exactly the opposite. If the front roll center is below
the rear, and the roll axis is made steeper (raising rear roll center or
lowering front) the car tends to "tip over" onto the outside front in a corner,
overloading it. Lowering the rear roll center increases the distance that the
center of gravity has over the roll center. This increases its lever arm over
the roll center, hence more body roll and weight pulled off the inside rear and
transfered to the outside rear.

here is where i get fuzzy. i dont think we can consider the front and rear
systems in isolation since they are coupled by the chassis. or at least, i dont
have a good answer for those that say i cant :)
is there a substantial effect on corner weights caused by the car twisting
under roll due to the inclined axis? >>
Yes, that's the way I understand it. If the weight transfers about an inclined
axis, more of it transfers to the outside wheel at the low end of the axis. A
flat roll axis will produce weight transfer where the front and rear of the car
are less related to one another.
