Torsion bars for better handling; your experience?

I agree. I would not advise someone to start off with 1.14" on a 100% street only car. And a car and owner that's not had any previous suspension mods to car.

There's a lot of personal preference here. Maybe if someone already had 1", then wanted to explore more.. Then try 1.14".

I had .99" for 10+ years. And it was my only car then. When I went 1.14" is was a secondary car.

What size tire/wheel do you run? You look to have much more sidewall than I do, and I have to assume that dampens the ride and affects handling with those 1.14' bars. I think @MRGTX has a larger diameter wheel and perhaps that's the reason it is a bit harsh on the street.
I already get understeer with my 1.08 bars, so I don't even think about putting a stiffer bar on mine. Now I do only have a 235 tire on the front due to my wheel choice and I'm sure that has something to do with it. Since my wheels aren't available with the correct offset/width, I'll likely eventually get them widened to accommodate a 275 on the front. I'm not doing anything to the suspension until I can get a wider wheel up front. Overall, I think my car handles great on the autocross.
