I'm thinking of adding the AWR engine mount to my list of small things to do to the 2, but I am curious as to the feel for daily driving. Are the vibrations really noticeable? Say if I had a random person sit in my car would they be like "why does your car shake"? I already DD/commute 100 miles a day with H&R springs so I can take a little discomfort if the rewards are worth it.
