I had Vibratechnics mounts in my mkiv - I did think 'what have I done' when I drove it for the first time.
They did quieten down, but I was never happy.
In terms of driving feels, they really sharpened the mkiv drivetrain, but in terms of acoustics, they were noisy. Fine for a track car, not for my then daily drive.
Hope yours settle in a bit, and that in 2k or so, they feel / sound better!
yeah main issue with mine is centre dashboard rattle. if i can take those panels off, tighten any screw and sound deaden the touching bits of plastic that will make a massive difference so going to have to give it a go first and see how i get on
