Update on new PST 1.03 Torsion bars.

I just want to know what the wheel rate is on them. Been trying to get it from PST since they did the re-clock on them. Maybe before then? I run Firm Feel's 1.12" bars on my Duster, but its set up fairly aggressive. Still, with the Hotchkis shocks on it I wouldn't even go as far as to say its "harsh", it feels very much similar in ride quality to my g/f's 2013 mustang with premium suspension. I had a set of 1" bars on it before, and those were too soft. Trying to figure out if I want to go with the 1.03" bars from PST for my slightly more mild Dart. Its either that or 1.06" bars from Firm Feel, which I'm starting to lean toward simply because I know exactly what I'll get, including wheel rate. And since the Dart is on a longer wheelbase I may just go with the bigger 1.06" bars anyway. As long as you go with a good set of shocks, you'll have a hard time making the suspension "too stiff". It'll just handle better. I still run Helwig sway bars on my Duster, so my effective wheel rate is frequently even higher than the advertised 300 lb/in on the 1.12" bars. I'm sure the PST bars are somewhere between 200 and 250 lb/in, but that's a pretty big range still. Realistically they're probably 220-230 lb/in. The Just Suspension 1" bars were probably in the 185-200 range, but there's no published wheel rate on those either.

I wish I could help you on that but I don't know either.
All I know for sure is the car used to have about a 3" dip when crossing a local bump I went through all the time, and now it has about one inch of dip at the same speed.





BTW, T-beast, what size t-bar did you start with?

I had 890's on before and changed to 1.03's.





Sounds about right I put the 1" just suspension bars (on sale) in my '70 duster when I put in the 360 and it made a world of difference. It seems to be a trait of t-bar suspension raising the spring rate really doesn't affect the ride much at all. Now I just need the rest of the suspension parts to complement the springs Question since t-bars rotate instead of compress how is the rate measured in pounds/inch?

Thats kind of how it feels to me also.
The ride didn't seem to change a lot, but the travel of the suspension shortened.
When I put poly bushings all around (including the stabilizers) I heard and felt a little more road noise and feel, but I don't care about that either as it is totally worth the benefits to me.
