UMI Motor Mounts in LS2
Gentlemen:
My ride is a 06 V, and I need motor mounts BADLY. I'm very interested in the UMI Mounts, but I see occasional complaints of unacceptable cabin noise/vibrations. It seems to me that most of those complaining of unacceptable vibrations have the LS2 engine.
I get that typical vibration at around 2K rpm, and at low speeds in parking lots, etc., the car vibrates so that my headliner buzzes. I don't want more of that kind of noise.
So I'm trying this poll thing here, if I can make it work. If you are running UMI mounts, please report to us the type of engine you have and if you have unacceptable vibrations or not.
Thanks brothas!

I'm handsome and special. I think.
Anyway, I'm glad you posted this poll. I've had the exact same question for a while. Now that my new camshaft is in, I can tell that my stock motor mounts are getting hammered a lot harder than usual and doubt they'll last a whole lot longer.

I have an LS2 with headers. With the UMI mounts, I noticed a small amount of extra vibes and didn't really stress it. It only seemed to get worse after I changed out the trans mount with a CS mount.
With the UMI and CS mount, the vibes are pretty decent. With the stock trans mount, It didn't bother me much if at all.
There is vibes at around 2k-2500, just like mentioned above... I can live with it. Some people can't.
I haven't noticed any noticeable idle vibes... regardless of pre- or post-transmission mount change.

I hear you. That was my concern before I actually purchased the UMI mounts. Anything stiffer than stock will vibrate. But there's unbearable and mild. I'd say you're safe with UMI mounts.

06 LS2 all stock, no mods at all.
Installed UMIs a few weeks ago. There is some noticeable vibration at low idle ... it's kind of like a harmonic.
But it's not at an RPM that is at normal operating speed ... only noticeable at idle.
It's a heckuva lot better than the clunking and banging from the stock units.
