The vibratechnics mounts are not harsh at all. Miles comfier that even an insert. Ths mount is very harsh, and even more so with the dogbone bush.
Had a golf r in a few weeks back, had a poly insert bush fitted and couldn't leave it in D at the lights. Replaced with both vt mounts and it doesn't feel any different in N or D. Very happy result.
The Vwr subframe mount isnt made by vt any more and is poly rather than rubber. Not very smooth.
