My driver's side rear is sitting almost half inch lower that the right. Never noticed it before. I did put on the GT2 sway bar, but that's not rocket science.

What is the most common cause of one corner to sag?

I was very careful to make sure both drop links on the sway bar were not loaded. I installed the drop links with the car under load. Can the sway bar even lower one side of the car?

 

ill come sit on the passenger side so you feel better.

 

motor mounts? coil springs?

 

Mine similar but supposedly within Porsche allowable tolerances.

 

Sometimes it takes a few days to settle if you've had it jacked up.
Might want to try it with the stock drop links and see if that corrects?

 

you said it was loaded..was it on a lift?

stock coil springs?

 

I Jacked up one side at a time and put railroad tie blocks under each wheel. I used jack stands as a safety measure, but left them 1/2" short so that the full weight of the car was on the wheels/blocks.

Yes, stock coil springs.
I installed the sway bar first, then the drop links. I adjusted both links so that they were neutral (no tension up or down, then tightened the lock nuts.

 

Well doesnt sound like its the sway bar or links....how are the links set up now?

No breaks in any of the springs?

 

Mine installed on a lift and no issues. Original droplinks
