Torsion bars for better handling; your experience?

I just did the PST 1.03 torsion bars on my Duster, as well as stock upper control arms with Moog problem solver bushings. The lowers I used the stiffening plates with the Delrin bushings and pivots. as well as QA adjustable strut rods from BAC and a 1" or so Hellwig sway bar. KYB gas shocks on all 4 corners which made a big difference, but the verdict is still out on them. I'm still riding on funky 15" wheels and tires like 275/60 on the back and 215/60 on the front which looks cool, but leaves room for improvement. I'm using going to 17" Mustang Bullet wheels all around which are not my first choice, but at $25 a piece I couldn't pass them and gives it the Torq Thrust look which is my favorite wheel anyway. I did think of spending big money on "tubular" stuff which looks cool and probably works great in the right application but after taking the invaluable advice of @72bluNblu who has some great ideas I decided to throw a little money at what I already have and save the money on stuff we probably don't need for something else like my 72 Demon project which will be getting pretty much the same treatment as well as a slant 6/904 to a nasty 340/727 that a buddy is swapping for a 500 inch motor in his Duster
