Hello 914'ers
I need to adjust and calibrate my front suspension. I installed the new torsion bars while the car was on the lift and it now looks like it could chase a ford raptor through the woods. 1: Is there a procedure for installing these and what angle the a-arm should be at? 2: Should they be done at ride height and then adjusted by the torsion bar adjustment bolt ?  thank you ben |

Index them to get the range of ride height you want
Then fine tune on corner balance scales |

Bars have to be indexed before installation. Most repair manuals should cover this. Adjusters are just used for minor up or down of 10-20 mm.

Look at the camber of the rear wheel. Roll your car back and forth a bit to settle the suspension.

Ri914, your pictures shows how far off it is. With car weight on suspension that front A-arm should be horizontal as a good start point. If you have purchased stiffer bars you might need to index them on the lift raising the front suspension with like a transmission jack before torsion bar is set. Mark

Thanks for the explanation. I knew they had to be way off. Fingers crossed I don't have to roll the fenders. |
