Torsion bars for better handling; your experience?

are you not limiting the suspension /body roll when you put in super stiff springs/ torsion bars?....isn't that why it is done?....so why not just limit it completely, providing you are not going over any whoop-de-doos and need suspension travel....its not like you are worried about hitting a rut or bouncing off the cushion needing suspension travel. Mainly it is a pole-putt on a flat (parking lot) surface.
In general, the goal is to run the softest suspension that will work well. The math for the physics and engineering is in Carrol Smith's Tune to Win but I think that sums it up. The better traction of tires in general has upped the roll rates and therefore the resistance needed.
