Those would be easier to install than say solid bushings, but what if the subframe bushings are pretty shot, I can't imagine that putting in the sleeves will be anywhere as good as solid bushings or new std bushings.
Yes I think the inserts along with the rear subframe, rear diff and trans bushings I already did should be the final nail in the coffin for the drivetrain slop. Still considering motor mounts, but I have yet to find anyone who has them in a sedan. They will probably be ok, but I worry about NVH with the motor mounts for some reason.

I’ll be picking up a set of poly motor mounts from Z1, I can’t imagine the NVH having a drastic change paired with the existing poly bushings we already have and inserts I’ve installed.

Where is A & D?
My car had 35k miles at the time I installed these, as for the Aphabet you’re trying to make come into play I think it has something to do with us with the G37 platform having steel rear subframes and older platforms having aluminum subframes so maybe they get the missing letters for extra support?

Awesome! Let me know what you think of them. Do you have a sedan?
What kind of difference did you feel with the sub frame bushing collars? They are on sale now for BF, if I don't get them, I will always wonder. I wish I didn't have to put the money in.
Looks like I am getting all of it, during Black Friday. My friend thinks it needs a flex disk aka Guibo, figure, I might as well get one with the diff being out. Where might I get one?

I've been eyeballing these for a few years now, and have lifted an opinion that the NVH is pretty minimal, less than Z1's poly transmission mount (which I have, per the OP's lead on that one.)
I'd love to hear current discussion on these poly motor mounts. Where are you on this project?
I've had two experiences with poly engine mounts and they significantly raised NVH. Granted, one was on a friend's well-used four-banger Sentra SE-R and the other on our SE-R race car.
No experience or anectdotal evidence with the smoother 6-cylinder G37.
These collars went completely under my radar. Just found out about them from a comment by ezbme today. So who's got 'em, and what do you think?
Seems like all the usual suspects here are interested. Figured 4DRZ would install them during his lunch break, LOL.
Haha! Yes, these have been on my radar and I'll probably do them this year. I think I held off for a while due to Z1's service being just awful for my tune. I am surprised you are just now hearing about these. I know they have been brought up a few times elsewhere.

I am surprised to hear you say our V-6 is smoother than anything else, let alone an inline 4 cylinder.

So about those motor mounts... got them installed yet? Thoughts? NVH?
