Questions about torsion bars?
I try!
I do love the Firm Feel torsion bars. The only issue I've ever had with them is they powder coat the hex ends of their bars when they powder coat the bars. It's great on the bars, but the additional thickness on the hex ends can make them harder to install on some cars. I just strip the powder coating off the hexes before install them now. I run FFI 1.12" bars on my Challenger and my Duster, and have a set of 1.06's for my EL5 GT. I've got 60k miles on the set in my Challenger with no issues at all. They are more expensive, but they're great. I'm sure the PST bars are too, lots of folks happy with the 1.03's from PST and as I said before I'm sure most of the price difference is in the manufacturing
quantity, not the quality.
