Replaced the H&R springs I had on the vehicle with Eibach springs and immediately noticed that after uninstalling the H&R, the strut/shock (rear) is leaking!!!:1zhelp: Installer of the Eibach springs is not at fault...as I am most confident in their ability and experience dealing with changing out springs. The only culprit we can come up with: H&R springs or regular wear/faulty strut (later of which is highly unlikely). Considering that the leakage started IMMEDIATELY after replacing the H&Rs w/Eibachs (keeping in mind the the Eibachs raise the car by about 1/2" in comparison to the H&R...in the rear), my guess is that riding that aggressively low with the H&Rs has compromised the struts to the point that when reversing the lowering effects of the H&Rs, the struts have such adverse reaction. This was verified by the BMW dealer. Be warned, BMW struts were priced out at ~$1500+ each plus labor AND under such circumstances are not covered by factory warranty!
