I have had this problem for as long as I can remember, and would finally like to do something about it. The car sits noticeably lower in the drivers-side rear, than on the passenger side, almost an inch lower. Today I looked at the Eibachs and Bilsteins when I had the wheels off, and couldn't see anything obvious. After putting the new wheels on and lowering the car off the jack, it appeared to be level. However, after I drove it and got out, it was sagging in the drivers rear again (yea, I know I need to lose weight...). Any suggestions on what this might be? Thanks.
