PST 1.03 torsion bars

[70ChargerRT]

The 1.15" bars were actually made by XV Motorsports but sold through Bergman Auto Craft.

The 1.0 bars are the top 2, the 1.15" bars are the bottom 2.

Peter Bergman had leftover stock from when he worked with XV. I got mine at a great price but that was 9 years ago. Hotchkis sells similar sizes. There are other options too from what I have heard.

I think the 1.03 bars are a better riding bar but if your car is lowered pretty low like mine is in the front the 1.03 will bottom out on potholes and so forth but not very hard, due to very little travel suspension. I do have adjustable shocks but I don’t want them too stiff. A bar like that 1.15 would definitely be better for lowered cars. Now that my car is settled in I’m going to crank it up 1” and see if that’ll take care of it.

Yeah. I’m running Viking dual adjustable. They are way better but way higher.

Kinda relative, Motons for a Viper are like $10 grand ‍

I had the Hotchkis 1.10 bars in my '70 Cuda along with their Fox Shocks. Great combo, rode and handled amazing! Summit has the Hotchkis 1.10 Hotchkis Sport Suspension 19367 Hotchkis Sport Suspension Torsion Bars | Summit Racing

$700!!! That’s like $400 more than the PST Bars.

The PST 1.03's are the best bang for the buck out there imo.

The Hotchkis stuff is always overpriced.
I want to support American businesses if their prices are not double what their competitors prices are.

you make a good point about ride height.

I have 1.00" diameter Firm Feel torsion bars with tuned Bilsteins, Hotchkis rear leafs, Hotchkis Front sway bar and Firm Feel rear sway bar. Handling is excellent.

I drove another FBBO member's car (69 Coronet) that has .096" diameter bars with Bilsteins and non-stock rear leafs and his car also handles excellent.

1.03" will be stiffer than 1.00". I'm thinking anything larger than the largest stock offering (.092") will be noticeable, but 1.03" is not necessarily the minimum diameter required. It depends on the car and the overall setup.

Anyone have header interference running 1.0+" bars?

 

[Kern Dog]

I thought about this question before.

Anyone have header interference running 1.0+" bars?

It occurred to me that if the bars are increased in size from .88 to even 1.15, that is .27”, barely wider than 1/8” each side of center. I hope that nobody has headers that are within 1/8” of their torsion bars.
Maybe the cheaper headers are. I had 2 sets of Hooker headers before I cracked open the wallet for the TTIs. Mine clear.

How do you like those Hotchkis rear leafs? 1” lower?

I have some tight ones but engine masters proved we can hammer the crap out of them and not kill power!

yes, 1" lower, but I run 275/60/15 (28" tall) rears so I can't tell. Front tires are 215/60/15. The car does well in turns and in the 1/4 mile. However, since the stance has a 1" rake, it would probably do even better if I had zero rake and the same size tires all around.

I was just wondering because when I put my car back together, I had a brand new set of superstock springs put up and I thought about using the Hotchkis 1 inch lowered springs but I went ahead and used the superstock springs. They did set up way too high when I first put them on, but after driving it for about 500 miles they settled right in and dropped at least an inch. I did use a 1 inch lowering block with them also. I used 285/40/17 out back and 245/45/17 up front. I am going to crank it up a bit in the front because it has settled in also and I’m bottoming out on potholes because I have very little suspension travel but not hitting too hard.

@70ChargerRT - that's a BITCHIN' looking Charger. That paint really pops in that lighting.

Up front on mine I also have 2" drop spindles from Magnum Force. That allows me to have my front dropped a bit without turning the torsion bars down too much.
