My 2001 325i has the sports package. The rear shock mounts were shot and I could tell the shocks were not doing to well at 56k miles. I picked up a set of Bilstein sport shocks, Eibach prokit springs, new rear shock mounts and did the install myself. WOW

what an improvement. The car just sticks and is much crisper in the steering feel. No more floatly wishy washy feeling in turns. The shocks were dead, if I pushed both font struts down, only one would reboud slighly, they other was dead.
Anyone thinking of upgrading suspension should not hesitate like I did. I thought the ride would be harsh or it would clunk. It is firmer, but more solid and feels right.
It's been about a month and I have not taken a picture yet. It's lower by about a half inch, looks good too. I 'll post some after my wash tomorrow.
