Torsion bars for better handling; your experience?

on my duster which is bb and t56, I have 1" bars, hellwig tube sway bar, moog offset upper bushings, reinforced upper shock mounts, stiffner plates on the lower control arms, expo 6 leaf with delrin front eye bushings, hotchkis Fox shocks. Cordoba front brakes and explorer disc 8.8 rear. 17s. I used to have the kyb shocks, I noticed a difference, but not a big enough difference to justify those shocks as an upgrade, for the cost. I also have problem with the upper shock bushing on the hotchkis shocks, the bushings shear off i wind up finding what looks like a calamari ring somewhere in the engine compartment and what's left of the bushing will fit inside the hole. I've been told that is common with that style upper shock mount. I also wonder if brand of tb has any effect, this car handles great but rides stiff. It honestly gets old sometimes. If coarse we don't have the nicest roads here in nj.
