Depending on Ballast (you) might want to raise the left a bit extra.. (IMG:style_emoticons/default/lol-2.gif) (IMG:style_emoticons/default/driving.gif)

I'm 179 lbs. Think the xtra is probably not needed.
Likely to be 10lbs less by end of summer....... GN QUOTE(sixnotfour @ Jul 4 2021, 07:06 PM)  Depending on Ballast (you) might want to raise the left a bit extra.. (IMG:style_emoticons/default/lol-2.gif) (IMG:style_emoticons/default/driving.gif) |

QUOTE(Gatornapper @ Jul 2 2021, 07:06 AM) I have the service record from the local Porsche dealer that about 3,000 miles prior to my getting the car, their shop had replaced the left rear trailing arm bushings. Was the camber set properly on the rear after the work was done? If they didnt shim the rear control arms properly it could result in a drop on one side. I would look at that and overall corner balance, but even then, these chassis were hand made and they all have some level of variance |

FYI -
Instructions on how to correctly set the front torsion bars to spec are found in Chapter 7 of the Haynes Manual, Section 16, p. 106. What's weird is the size of the torsion bar adjustment bolts. 11mm wrench is too small, 12mm too big. QUOTE(Gatornapper @ Jul 7 2021, 08:18 AM) I'm 179 lbs. Think the xtra is probably not needed.

George -
Thank you again for your perfect analysis. But your diagnosis was not only correct, but solved another more important problem that I did not know I had. Setting the torsion bars to spec did indeed solve the height difference between left and right. But it did something far more important. Having never checked the torsion bar settings, I found both to be completely loose. This means that the bars (springs) were not in effect until after the suspension was activated by a bump in the road or a turn. There was slack on both bars! Setting both bars to spec leveled out the car, AND tightened up the handling noticeably - to my great pleasure. It was almost as if I added sway bars! (winter project). GN QUOTE(dr914@autoatlanta.com @ Jul 2 2021, 03:45 PM) jack the front slightly from the center of the cross member to take most of the weight off of the front (do not have to lift the tires off of the ground) and see if the rear straightens out. If so the front torsion bars are out of adjustment |

Yes, they are a bit munged up for some reason.....if I file the flats down, I'm sure 11mm will work........next time car is on lift I'll do that.....weird how they got munged up........
Thanks!
