Ok I started working on the rear tonight and ran into a possible problem. I got the driver side out and all apart, went to put the eibach spring in and noticed it is taller then the stock spring by a coil? Is this normal? Every car I ever lowered the aftmarket spring was shorter than the stock. The listed part number on the box is 2552.140 which I believe is correct. The springs themselves say 2552.101 and 2552.102 I guess I'm gonna have to call tire rack in the morning if no one can help.
