Looking at re indexing my torsion bars on the back of my 86 non turbo 944 while i have the torsion housing dropped slightly to replace clutch. Is there a general recognized amount of splines to achieve an approximate drop? i.e 3 inner splines up and 1 outer down gives 25mm?? Cheers. |

There is: I have a guide somewhere which explains it. I will quote a part of it and youll be able to find it using Google. "The torsion bar has 40 splines on one end and 44 on the other end. That means that the splines on the 40 spline end are separated by 9 degrees. The 44 spline end is separated by 8 degrees and 10 minutes (60 minutes = 1 degree). That means that the rotation of the torsion bar can be set to within 9 minus 8o10’ i.e. 50 minutes of angle. A 50 minutes of angle change in the torsion bar will give roughly a 6.5mm change in the ride height. So, to lower the car by 6.5mm (a 50 minute of angle change) you would pull the torsion bar out from its inner mount, rotate it one spline counter clockwise (CCW) and re insert it, then you would put the end cap on 1 spline further in the CW direction. If you wanted to lower the rear 20mm you could rotate the inner torsion bar by 3 splines CCW and you would rotate the end cap by 3 splines CW. Ie 3x50 minutes change = 3x6.5mm = 19.5mm overall change)" Simon |

Yes thanks for the help on that! I had found that paragraph about 50minutes being about 6.5mm but being as thick as two short planks hadn't worked out the other bit
