Well, 1/2 a year and 12K miles later, I replaced all the springs and dampers this weekend. I went for the Sport Konis.
there was a 20% discount thru tire rack, so it was time and the price was right.
bit of a learning curve. both in how to use tools and how to do procedure.
Bought Stock parts thru AutoHaus.
First side took more than twice as long as second. I'm still not able to talk about it
without my hand shaking!
Biggest problem was for an E36 M3 you have to modify the original damper housing to accept the adjustable insert. Side cutting tool recommended. my sawzall worked as well.
U-tube video very helpful and recommended. I owe this guy a beer or two!http://www.youtube.com/watch?v=qzNZCnUYtzo
but did not show possible problems of insert hanging up inside stock damper and not seating.
(of course mine did)
Never worked with a spring compressor before so that had a learning curve too, as well as getting the old springs out and new back in.
I now realize I had a "lowered look" as the rear springs had compressed about an inch. front looks slightly higher too now. ride I think is better.
Note: rear koni's are adjustable only by releasing the lower bolt and compressing the damper, then rotating by 180' up to 720'.
Front adjustment tabs in engine compartment (E36) not readily accessible to stock plastic adjusting tool provided. It's too wide. I will have to fabricate a "fork" out of an old screwdriver as metal can be narrower and still strong enough. There are some other tricks I learned as well. If your interested, ask me.
See ya at the track! (If Michelle let's me drive the car!)
