Don't forget that, unless you re-adjust the suspension, when you raise
the rear, you are also changing the camber towards positive and
increasing toe-out.  Having less negative camber on the rear will
increase oversteer (or reduce understeer) and the end result would be
more neutral handling on an understeering car.  But it's not just a
direct result of the increased ride height, but also of the decreased
neg. camber. Toe out will probably result in twitchy handling.  Yes...
so many variables can be confusing at times...
