I just got done installing the 034 aluminum subframe bushings along with a poly bushing for the steering rack from USRT.
Man what a difference. Everything feels so much nicer in the front end. And it's not really any harsher than before. Everything just feels connected. The install was very easy to do as well.
Next upgrade will be a TT sway bar(I'm running st coils and they have the provision for the end links) and some harder strut mounts(either UM bushings or camber plates).
FYI I I've got a vr6 so with a 1.8t you might get added vibrations.
