Car not level

I have a 1973 911T that is exactly 1 inch lower on the passenger's side (when viewed from the rear) than the driver's side.

Is this a spring plate bushing, weak torsion bar or something else? What would possibly be the detailed fix for this?

This car is a garage queen, driven about every two weeks on the Blue Ridge Parkway and in the Smokies.It's not autoxed or driven hard but I would like it to sit level. Any help or comments are appreciated.

Does the car sit level when you are in it? Ours sits high on the left with no one in it since I weight a little over 200# and it was set and aligned to be level with me inside. Might be a good idea to get a four wheel alignment done by a shop that knows Porsches as they could tell you if anything has worn out or slipped, etc.

The car is not level empty.

When I jacked up the passenger side to inspect it, it was perfectly level when it was lowered, until driven.

When I got it back in the garage it was 1 inch lower on the passenger side again.

On the driver's side when I do this it is higher until driven (the suspension loads itself I've heard?).

Sounds to me like I've got a weak component on this nearly 27 year old 911. I probably should at least replace all the bushings on the car anyway.

By the way, the car has less than 60,000 total miles on it.

Have you checked to see if the rear coil over springs on the shock are in the cup? Sometimes when jacking up the car, the top of the spring gets misaligned, causing one side to be higher than the other. Especially with old saggy springs. You MIGHT correct the problem with new shocks and springs.

In any event, most alignment shops give free advice as to how to correct stuff like this.

Good luck.

I have a '73 911-T coupe which sits lower on the left side. I am currently replacing the spring plate bushings on both sides. Before I commenced work I had the car's corner weights checked at a race car shop (equiped with wheel scales and electronic readouts). I was surprised to learn that with me in the car and a half load of fuel that the corner weights were within spec. So why does the car sit lower on one side? Could be that one torsion bar is more tired than the other; (my car has over 100K miles on it) or the spring arms need to be reset at the correct degree of inclination with the addition of new rubber bushings. I haven't completed the work yet but hope to have the car appearing level after I'm done. I'm trying the new Neatrix bushings for the spring arms. I think that after 27 years of service that all the rubber bushings are mishaped, tired and cracked. I found the spring arm bushing coverplate quite rusty and rust pitting on the surface of the torsion bar tube outer socket (where the spring arm bushing fits). Finally, before doing alot of wrench work I think it might be wise to have the alignment and corner weights checked by a competent Porsche shop. By the way, your car has only torsion bars (for its springing system) not coilovers.
