2003 Volvo S40 - Vibrations after poly engine mounts installed
Installed poly inserts on the front / rear engine mounts with the custom 10.5 ID sleeves. Makes vibrations a bit stronger and as a result I know what is loose in the car. Headrest, dash, center console are main noise makers and I've already picked up some felt and padded foam to try and mitigate the noise.
UPDATE - I've since gone back to the oem mounts. The vibrations at idle didn't bother me too much, most of it was from the headrest. GF didn't like it though and wouldn't drive with me :D
