Advice on torsion bar size needed

qlander · 05-17-2006, 09:56 AM

I did things backwards. Instead of changing T-bars first, I instead tackled the shocks first.
Went with Bilsteins sports all around.

Now I'm ready to try for the T-bars. I did a search and have a few comments/questions for you all.

The car is a 88 turbo cab. No track time planned at this time.
I do enjoy quick responses.
Currently stock except for the shock upgrade.

It does appear to to bobble at the rear quite a bit (read in a prevoius post that this is a common malady of 80's P-cars).
I don't mind a firmer ride since I'm just about the only one who drives it (daily).

1.How big should I go 22/28 or 22/29? Bigger, Differnt mix?

2. Hollow vs. solid? I read a scary thread about cracked hollows.

3. What about the spring plates. Just replace bushings?

I'm leaving the sway bars alone for now, that is what i learned from the posts.

Any other comments/suggestions would be appeciated.

Thanks,

Q.

For street here is a good street set up. Lots of opinions out there, not saying I am right, but this is what I would do if it were my car based on your description and use.

1. 22/29 or 22/30. A little more rear spring rate from these combo's make a nice handling 911, especially a turbo (lots of power, more rear end weight)

2. Hollow, Elephant bars are perfect fit, hollow (lighter) plated and plugged. They are almost to nice to install! They will not be any more prone to cracking then any other bar.

3. Use Neatrix to save cost, use Elephant Polybronze for a real good solution that is not too much cash. (I have installed and driven both more than once, and it really depends on your wallet) For a street car you will be fine with the Neatrix. I would not use the harder plastic bushings that are available.

Your car has good stock sway bars on it now, upgrade them last if you still want some more performance or adjustability.

You may want to look at a set of front Polybronze while you have it apart (good time to do it). Modest investment to replace a typicaly worn part.

Check your ball joints and tierods if you didn't when you replaced your strut/shocks.

Sounds like a nice car,

Cheers

Thnaks for the response. I did notice that turbos usually did add an extra mm in the back. So I think 22/29 will most lkely be the setup.

I recently put Bilsteins sports all around and turbo tie rods. Also I added a triangulated strut brace from Rennline...I think this made a huge difference because I have a Targa. Also a Cab would benefit from the triangulated brace.

I was happy with the results but the back end still "wagged" so I ordered new TB's.

I just got my 22/29 T Bar's from Pelican yesterday and Speedware Motorsports will be putting them in next Friday. I also went with Neatrix springplace bushings and some new A-arm bushings.

I did a bunch of reading and that seems like a good set up for spirited driving and random DE events.
