I just finished the repair for my 2001 on Friday. I purchased Bilstein shocks from bavauto, and the rear suspension kit from deutschepartsusa on e bay. I normally do my own work, but decided to take it to a shop that only does suspension work in Camden NJ. The shocks worked out fine, many of the parts from the e bay kit didnt fit correctly and had to be modified. It added to the labor. In the end $1150 labor, $150 shocks, $361 for kit. It does however ride and handle like new. 125K miles.
