torsion bar and ps box upgrade

1.06" torsion bars aren't too big for a daily driver, as long as you pair them with the right shocks. I run 1.12" torsion bars from Firm Feel on my Duster, and with the Hotchkis Fox shocks I run with them they're awesome on the street.

What is the application for the car though? Just curious, because the SS springs aren't something you really want if handling is your end goal. They lift the rear of the car too much, are too stiff, and aren't the same spring rate or arch side to side. They're great for hooking in a straight line, but corners aren't what they were designed for.
