Please do this at your own risk. I am not responsible if you break anything. End legal mumbo jumbo.
Okay, to begin, this was performed on a 1993 318is, two doors, E36 with a Motorsport suspension from the factory, M42, automatic tranny, black on black, build date 01/1993. Your car may differ from mine. If it does, figure it out.
This DIY was also only performed with Bilstein Sport Shocks, using the springs that are in place. Other Bilstein models may be different, and if you want to change the springs, don't ask me, I didn't do it.
Okay, on with the DIY!!!
Note: Some of the pictures have the new Bilsteins in place when I am talking about taking out the old ones. I got excited and went through half of the install and then relized that I wanted to take pics.
First off, jack the rear of the car up. I put jack stands under the jack holes and went to it.
Take off the wheels...
Place a jack under the rear control arm and jack up a bit. This is so that the control arm isn't under a lot of pressure.
To get to the Upper Shock Mount (USM), the rear speakers need to come out. Climb inside the car and take off the speaker cover/grill.
