I am the fussiest man alive when it comes to NVH
OEM is way too soft, aftermarket way too stiff, but it's subjective. I can see why VW fit such soggy engine mounts because their engines aren't the smoothest.
What about OEM diesel or MK6, or even MK7 mounts? Any improvements? Weird thing is, when I ever I drive MK7 rental cars, I don't even notice the engine mounts. When ever I drive mine, I am very aware of the motor flopping about. I've got the Vibratechnics dogbone setup and OEM sides.
I've read in PPC mag that you can fill the voids in new OEM ones with liquid rubber or soft poly which is apparently a good compromise. Might try that one day.
