Thread: BMW Z3 rear shock mount options (all inclusive).

I plan on making a few of these threads to be included in The Neo Z3 Manifesto. It will be nice to have a list of all of the available replacements/upgrades for a specific part. This is the first of such threads.
If I've left anything out, please post below and I will add it to the list. If I've made a mistake, please correct me.

Keep in mind that while I've tried to provide the most relevant and informative link, it's possible you might find the product for sale elsewhere, and possibly cheaper.
Also, 14mm and larger inner diameters are available from a few of the manufacturers below (Ground Control comes to mind) if your shock rod pin has that kind of girth.

Street/rubber/urethane options:

Almost every single item above had an outdated link, and some needed part number updates. I've gone through the entire list and updated everything, including adding a new option (Powerlfex) and marking anything NLA that I could not find.

So as of today (2021-02-25) the list is 100% good again.
