Crazy! You use Otto too? Small world. I've had a fair bit of work done there. He's a good guy. His accent is hilarious. Now that I don't live in an apartment or condo and actually have a place to work on it I try to do all my own work.
Even a 92 The E36 is a great car. It's not the fastest or the nicest but they are fantastic to drive. Definitley worth the headaches and money for the joy of driving it.
When they upgraded the suspension did you upgrade your Rear Shock Mounts as well? The RSMs are a common wear and failure point. They can cause the failure of the entire shock tower of theres too much stress.
