I use 23,5 mm and lowering angle 12 degrees and that works ok.

Hi again
I found that the lenght should be 676mm.
Inner splines 40 and gives a change of 9 degrees
Outer splinses 44 and gives a change of 8º 10,5’.

Zen, I'm running the 944 25.5mm torsion bars which were a good mix of track and street. It's on the tight side for street use but if you autox, hit track days, or frequently drive winding roads the setup is perfect. It never had any problem with my type 4 hanging off the back.

My old track/street setup

2L type 4
1303 lower control arms
modified 944 struts with kyb gr-2 inserts and eibach 12" 80lb/in. springs

86 944 club sport 25.5mm torsion bars
kyb gas-a-just shocks

I had the same question so I made a shot in the dark. I just put Sway-A-Way 28mm's on thinking they would be super stiff. (aircooled.net) I autocross so I was willing to sacrifice some comfort. No comfort lost. The car now feels solid & firm, no harshness at all. Red Koni's too, on second setting. Magic Carpet. I'm kicking it at the autocross now too. Just what the doktor ordered.
