Not much...I am on the E46 forums and it does not come up often...

Yep - anything rotating that's out of balance will typically cause increasing vibration as RPMs increase. Something that causes vibration at only low RPMs is either something that stops turning at higher RPMs, or an issue with an engine mount, which only transmits low-RPM vibrations through the engine into the chassis. That's why I still think this is engine-mount related.

I changed my engine mounts. It didn't really help.
