Torsion Bars for a 71T

[Jbizzle78]

Currently I have 22/28 torsion bars on my 1971 911T (15x4.5 steel wheels)and they are way to rough. I am looking for a nice ( stiff ride, for the street. what size bars would you guys recommend?

[dipso]

I have 21/26. I like them a lot.
I wanted 22/ 28 but my mechanic said that with the weight of my car, that would be to stiff.
I imagine a 71 is pretty light.

The weight ratio is very important.
There is a topic on this in the tech articles section.

I've also got 21/26 good but maybe the front would be better with the stock 19

nice and stiff, or nice but not stiff?? you put ) in your post so hard to interpret

how old are you bushings? that can make a big difference in NVH

[Jbizzle78]

Nice, but not too stiff. I have replaced the bushings as the car has gone through a full restoration I have upgraded the suspension with SC - bilstein greens. The rear seems fine, it's the front that seems to be really stiff

[RWebb]

what kind of bushings did you use?

[Chuck Moreland]

There are a number of variables that effect ride quality. Torsion bars are but one of them.

What do you have for:

- shocks
- bushings
- ride height

[Jbizzle78]

I think they are the poly graphite ones.

I used elephant rubber bushings everywhere and am very happy. I agree the front is a bit too stiff for our light cars although it is not enough to make it understeer. I've got the front red Koni gas which I like and the rear yellow sport gas Koni's recently replaced which I don't like. They are ok in the dry but on wet roads they don't feel predictable. I wanted new rear reds but they are no longer available in gas and I didn't want to have to recalibrate my Tbars for the normal red Koni.

then get rid of them as they almost surely your problem (or a problem)

re t-bar size, you might want to go with what Porsche used on the RS cars

or go back to stock -- the stiffer the bar you want to get rid of, the more likely you will be able to resell it if you do not like it

Now, the other big component of the total spring rate on a car is the tires - how old are yours?

what dimensions?

what brand & type?

(in other words, to save $$ you may want to replace the torsion bars last)

just add this all in to the answers to Chuck and you get the car all dialed in - restate your purpose (softer street, right?) and your budget
