So I finally tore into the suspension with another e36 guy, and we found that it was definitely bmw stuff under there, but most definitely not original to the car. It looks like the fronts at least were off a 95 (large perches, untapered springs and 95 struts mounts) and the rears were put together all wrong. Got the new front and rear sway bar links, shocks/struts, and mounts all replaced. It rides about 1000% better now, and no more knocking noises. I still want to get some proper springs in there that I at least know were designed for the car, but now its still got a good 3/4" rake. Here are some pics (didn't get many, was pretty pressed for time).
Ready for surgery:
Old front hardware:
Whatever springs these are:
Fresh Sachs shocks and Lemforder sway bar links
Re-secured the heat shield:
New heavy duty e46 cabrio RSM's with reinforcement plates:
Then it was time to get strapped into the 5 point Simpson harness and go for a spirited spin in Craig's turbo'd 325i track rat (only 2 bad pics because my head was pinned to the seat for most of the time).
Suspension is about 80% sorted, since we found out there are '95 perches in there, its a perfect opportunity to pick up some H&R OE Sport springs (which require the '95 large perch anyway). Next on the list is get the crappy window tint redone, fix the leaky power steering hose, brakes, get window regulator/slide deal sorted out, get a proper battery, and plenty more I'm probably not thinking of
