I've been having some odd noises coming from the steering while turning the wheel towards full lock while parking, so I pulled the front struts to re-grease the strut mounts to see if that helps at all. While I was in there I removed the fixed camber plates and added e90 drop hats. I had always heard they were a direct drop in, but once the whole stack with the top mount and various washers were installed there wasn't full thread engagement on the top nut. I ground down the tapered washer piece on the top hat to reduce the thickness and end up with a flat mounting surface like the factory mount, but I forgot to take a picture. This is the part I'm referring to, I shaved it down by about half. It is a steel insert and still had more thickness left than the original e30 top hat so it should still be more than strong enough.
With the added drop hats and removed fixed camber plates (add another 5mm or so to the front ride height), the stance is so much better. It could still be a bit lower all around, but for now this is perfect. All cleaned up for the picnic!
The z3 rack is now leaking quite a bit from both sides, so I am going to give rebuilding it (or a core if I can find one) a shot at some point in the near future. I found this thread: https://www.bimmerforums.com/forum/showthread.php?2153710-DIY-How-to-rebuild-your-Z3-short-ratio-rack-and-pinion. And this video (https://www.youtube.com/watch?v=W9drVXzCOuM) that are quite helpful. Seems like a tedious job but not impossible to do at home. Saving here for reference.
I changed the oil a few weeks ago too.
