I have a 2007 997.1 C2S with ~41k miles on it. I recently lowered it with HR springs (1k miles ago). I recently noticed my car is sitting lower on the driver side on the rear end. I measured it from ground to the arch of the wheel well and found the driver side is almost .25" lower then the driver side. I'm wondering what could possibly be wrong.

1) Is is possible the springs were incorrectly mounted? I never really paid attention to it before I lowered the car, so I cannot tell when it started sagging. I thought the springs can only be mounted one way.
2) Does it mean I need new shocks? With 41k miles on it, is it normal for shocks to go bad?

 

I'm curious what your ride height would be with you in the car.

 

did you do the HR yourself? I did mine and there is a certain was the end tip of the spring itself has to sit into a groove in the top hat. It's easy to have the spring slightly off and not sitting in the groove like it should. Happened to me when I did my first install. I readjusted the spring and that fixed it.

Shock issue is possible but with only 41K miles that would be weird...

 

maybe H&R made the driver side higher so that it would be even with the driver inside

 

I had it professionally installed. I'm also suspecting this since I see that the top hat have a slope to it and if the top of the spring is not properly slotted into the slope of the top hat, then it will obviously effect the height.

 

I suppose I can put a sack of rice on the passenger side to even it out!

 

Corner balanced?

 

Do you have a RHD or LHD? Mine is RHD and is slightly lower on one side (can remember which side but will check), and I've been told that it's "normal" for RHD cars since the car was originally designed and with weight balance for LHD. My X5 is also lower on one side as well.

 

Nope. I don't have coil overs. Just regular H&R lowering springs.

 

you laugh but I had my car corner balanced and they set it up like that somewhat so when I'm in it its even

 

Have you had your car corner balanced or more importantly aligned since lowering??

 

I've had it aligned but not corner balanced. I don't have coil-overs and I don't think it is possible to corner balance regular H&R springs.

 

you are correct. Springs with stock shocks cannot be corner balanced but most people with coilovers don't know that.

 

Is it possible it's a shock issue?

 

is the side that's lower, lower than you would expect for the H&R drop? or is it the side that's higher that isn't as low as you would expect?
