Spohn Pro-Touring Adjustable Rear Sway Bar

[Lue]

Hi Guys,

Is any one using this sway bar set up? I was looking to get some feed back..

Now you did it, I'm following you. :shock:

That bar should work fine.

It is more or less a adjustible copy of the HRParts&Stuff bar.

Funny thing is the HR bar was a refined/heavyduty version of a third gene Firebird bar.

I built the same thing for my Cutlass using a Fbody bar for the price of a heavyduty leaf spring clamp and poly bushing set.

I did get a HR bar after talking to the designer.Yet to try it.

I like it and don't at the same time. I was thinking of a similar setup for my car, but wanted to do the end links in a different way. My idea was to use a solid bar and have a CNC machined clamp on each end to hold the bar, which would then be linked with spherical rod ends to the car. The bar would not have any end link provision on it, and would instead just be round the whole way out. That way, I could have infinite adjustability and slide the clamp to wherever I wanted on the bar, thus increasing or decreasing it's rate due to the change in MA (Mechanical Advantage). Someone used to offer such a setup, but I can't remember who right now.

Also, are you thinking of this for a handling car or a drag car? If it is a drag car, there are better setups than this for your needs.

I was thinking more along the line of handling

I'd put my money into springs and shocks first...

Well, for handling, it really depends on what you have on your car now. Is the car stock? Does it have the factory big sway bars already? etc. There are a lot of improvements you can make using junkyard parts if you have an otherwise stock car. That bar is for a car that already has the basics done and needs fine tuning. Right now, my car has the basics done, and improving it is getting quite pricey...

I agree.. My car is all stock now, but what i'm trying to do is get a list of parts going so i can save up and know what i need. I already have f41 sway bars and braces.

Well, the factory front bar will be fine for whatever you choose to do. It may actually be a little too big. The rear bar is also fine for now. Your next step should be finding a fast ratio steering box from a G body (it is the fastest Saginaw box GM ever used, with the stiffest torsion bar!), and some better springs. I would also replace all the bushings in the front end with polyurethane, and replace the body mounts with polyurethane. Now, past that, the major problem with these cars is that the front suspension geometry is *ss backwards to where it should be. This is a complex problem to solve, and as of yet, there is no perfect solution to it. It is where I am at right now. I have the stuff for a tall spindle conversion which fixes the camber curve issue, and since I ordered offset cross shafts, it also fixes the caster issue as well. The real problem that is left is the bump steer issue! I have a few possible fixes for it ( different lower ball joints, dropped pitman arm and idler arm, dropped center link, etc) mapped out, but have yet to do the actual work of running a computer simulation of all possible solutions to find the right outcome. This is mainly doe to me not having access to a suitable program to do it. If anyone knows of a free application that will let me sim the suspension geometry, let me know. As always, I will share anything I find out on the forum for the benefit of all.
