Wanted to get some feedback from people who have been running Bimmerworld Performance or Group N motor mounts for several thousand miles or more.
I'm mostly interested in hearing if the NVH stabilizes at a certain mileage or if they progressively get softer due to being rubber instead of hydraulic. When are the stiffer mounts most noticeable? I've read about some resonance at 2k rpm; does this eventually settle down? Also probably too early to tell but how is the lifetime of these compared to stock mounts?
Any general feedback is welcomed too. Hoping to install my BW Performance mounts in the next couple months so I'd like to be aware of the benefits and idiosyncrasies, TIA
