I am also weighing which bushings to use front & rear (leaning towards all HD rubber), and one thing I rarely hear discussed is that rubber bushings increase the force required to move a suspension arm, compared to metal or poly bushings. Going to non-rubber bushings must ultimately reduce the spring rate and necessitate a change in damping, as well?

My concern is that if I change to a slicker bearing, I'll have to increase my torsion bar sizes to compensate for that loss in spring rate... and that my present shocks/struts will also no longer be appropriate.

At first glance, it seems that making these suspension changes is an all-or-nothing endeavor (change the dampers, bars, bushings, or keep it stock)?
