Torsion Bars... Best Diameter for a Lowered Street / Autocross car?

I run 1.12” Firm Feel torsion bars on my Duster with Hellwig front and rear sway bars, 120 lb/in rear springs, Hotchkis Fox shocks and 275/35/18’s in the front and 295/35/18’s our back. I also have SPC UCA’s, QA1 LCA’s, adjustable strut rods and BAC’s delrin bushings.

Based on your description, I think you’d be fine with 1.12” torsion bars. Especially if you’re lowered any significant amount.

My plan is almost identical to your setup on the Duster. Knowing what you do about your car's current handling, would you step down to 1.08, or up to 1.14 bars? As I look at options, those two sizes seem to be at a better price point than the 1.12 from Firm Feel. (I'm looking at BAC 1.08 and Sway Away 1.14). I'll be running the Hotchkis Fox shocks as well. Thanks
