Any idea why my driver's side is sagging?

[Jon '92 325ic]

Both camber and caster are more off on my driver's side than passenger's. It's visibly noticeable from the rear. Here's the #'s from the read out done with my last alignment:

DS (driver's side) front camber: -1.6
PS (passenger's side) front camber: -1.4

DS front caster: 8.1
PS front caster: 7.8

DS rear camber: -2.8
PS rear camber: -2.2

I'm guessing here, but maybe rear subframe bushing is more worn on driver's side because 80% of the time car is driven without any passengers?

Car has new bav auto springs and I had the front and rear struts/shocks replaced with BOGE OEMs when I had the springs installed. Also replaced front and rear upper and lower spring pads and upper strut mounts as well.

Any help is appreciated.

Thanks

Did you happen to measure ride height before and after the mods?

That's the first time I've ever heard of this problem.

Perhaps some of the suspension cognoscenti will weigh-in on this one...

Good luck!

This is the first time I have seen anyone besides me on this forum use the word cognoscienti.

I say the BavAuto springs are the problem.

How are your rear trailing arm bushings? Those are really what wear and change camber back there.

Oooh, that caster.

If all of the mounts are secure and not worn, measure the compressed height of the springs under load-soft or short spring. Last resort-have the unibody checked for damage. An alignment may or may not indicate if there is unibody damage. Even the best equipment will not detect it if the tech does a "quick and dirty" and only checks individual wheels.
Hopefully those hoofbeats are horses and not zebras. i.e. get ready for suspension bushings.
