Just finished installing Eibach lowering springs this weekend. Took about 4 hours cause I ran into a problem where I got the rear M14 bearing stuck. Make sure everything lines up before you push the camber arm up. Helps a lot to have a 2nd person jack up the camber arm while you're holding the wheel carrier in place and pushing in the M14 bolt.
