Torsion bars for better handling; your experience?

The difference in going from factory 318 bars (not sure the size, .89"??) to the 1" Just Suspension bars made a massive difference in handling with almost no change in ride quality on my '70 Duster. As has been said, it's actually kind of tough to get bars that are TOO big. The beauty of the Mopar torsion bar design moving all the weight loading to the center of the car makes it keep a nice ride with high spring rates much better than coil-sprung cars. I still need to bring the rest of the suspension up to snuff but I will probably go up to 1.06 or 1.12" bars at some point; planning on adjustable Viking shocks, front and rear Hellwig sway bars, and tubular UCAs. I also have to ditch these 15" Rallyes with fat-*** 60-series tires and get something lower-profile, these wheels and tires belong on a pickup truck lol.
