When looking into coilover solutions I've read that alot of people consider the OEM rear shock mounts to be inadequate and I've seen two main solutions.

The first is the Ground Control RSM upgrade Check about half way down the page of the first link for the RSM or check the second link:

The other option I have seen are the suggestions from UUC on getting upgraded OEM parts:

Anyone had experience with either of these or have any suggestions on which to pick? The Ground Control RSM looks like the way to go but I'd like to save a little money around the winter mod season.

If anyone could also look further down that main Ground Control BMW page and tell me what the "E36/46 trailing arm bearing kit" would be good for I really appreciate it :thumbup:

I saw the ones on the turner motorsport page and they look pretty good also, but it looks like the mount screws down into the base which seems like it might have a problem coming loose where the Ground Control RSM's are made from a single piece.

Would this make a difference?

I'm running the upgraded OEM setup that UUC recommends. Works great.

Replacing any suspension bushing with a spherical bearing will noticeably increase road noise. Unlesss you plan on frequently tracking your car, stick with stock rubber. If you are worried about the short lifespan of factory rubby, try polyurethane bushings.

wasn't there an upgrade that involved M3 RSM as well? I don't know much about it, but it would seem cheaper to me and still retain the NVH characteristics of stock RSMs.
