Bimmerworld Engine Mounts

[Consum3r]

Same combination and same experience, enough vibrations at initial start-up to let you know they aren't OE. When driving I don't notice it at all, occasional slight vibration at lights.

definitely wouldn't describe it as, "a shiatsu massaging chair" lol

Same here as well with combo and experience. Over time the vibration has decreased considerably, post the initial install it had me thinking I was going to swap the engine mounts out as it was considerably worse.

I put stock mounts back on that car, and it was like the angels sang the first time I started the car and it didn't vibrate my eyeballs out of my head.

The poly mounts are all different durometers. Have you compared the durometers of the BW mounts and the Revshift stuff?

Struggling find anything online regarding durometers with BW mounts to compare to Revshift

In my car (Bimmerworld Grp N mounts with RE transmission mounts), I found increasing revs to 1000 or 1100 rpm while idling helped with vibration.

I’ve noticed if I hold the revs at 1k rpm, whole car feels like stock. No NVH problems while cruising or giving the car some beans

How many miles of driving it take to decrease? Compared to post initial install and now, what would you say on a scale of 1 to 10, the NVH is like?

Call Bimmerworld. They'll definitely have info on their own mounts. Might know the Revshift values, too.

Yep, so now go change your idle speed settings

Your tolerance to NVH will certainly increase over those miles
