Transmission Mount Comparison (Master List)

[gferil]

I also have the UUC Option 1's (ordered in November, shipped in Jan) without the enforcer cups (actually I ordered those but after reading this helpful thread I decided not to install them, thanks Finnegan!), and I LOVE how they have improved the feel of the transmission. Also, the NVH that it added is awesome, totally brings a very "raw" sound to the car above 4K, but is still civil enough to be used as a daily driver, and when you combine it with the GruppeM intake I have...it's pure awesome-ness...if that's even a word.

Excellent!

This is one of those mods that 99% of folks agree on. The stock mounts are marshmallows, and really are inadequate to the HP/TQ of any of the inline 6s offered. Where you go from there is just a matter of desired effect and intended application.

Anyone running solid motor and tranny mounts?

Unless it's a 100% dedicated track beast, why would you want to?

Local Shop has these mounts from AKG - given the price, I'm assuming they are similar to Rogue mounts in terms of being ok for street driving - am I assuming too much? Should I just order the Rogue's? Thanks in advance

Those are poly mounts. And will have significant NVH. Unless this is a track car, I'd go with Rogue Neoprene.

I guess had I read the whole page I could have seen that - thanks for pointing that out

Yeah, but I'm long-winded (or shall we say "complete") at times. Don't mind the question, don't mind answering either.

Hey guys, I need an advice.

I was on a track day this Saturday, pushing the car pretty hard and unfortunately missed the shift from 3rd (@8000 rpm) to 4th twice during the day and got the grind noise. I wasn't pushing it in too hard so I just let it go back to neutral, pushed the clutch fully in again and put 4th in.

After the track day we had some street racing with 2 other guys (don't ask) and I noticed vibration noise @ 7000 rpm and higher. First I though it was smth in the glovebox at a weird frequency, but then I wanted to shift and I noticed bigger vibration in the gear stick and that it's the stick which is doing the noise (when I pushed the stick it just a lil bit down, it got louder).

The question is, are the transmission mounts weared out or did I mess up my gearbox? :-/

I tried it again later and the vibration wasn't that bad and a day after it was actually almost gone, but I still know that there's smth wrong and want to fix it. Thanks for any advice!

Dud you replace engine mount bolts?

No, the whole car is pretty much stock, except for AP racing kit and APEX wheels.

My car had vibration when the bolts cracked. It was after replacing aftermarket tranny mounts.

Do a search for the thread. You'll see the engine dropped on the passenger side.

Thanks a lot, I'll look into this!

What do you guys think of the UUC red isolated urethane engine mounts?

UUC site recommends them with the option 2 red urethane isolated tranny mounts.

[zubydafa]

sorry...one more question.

i could do UUC red isolated urethane engine and tranny mounts for $260 total
215 for the engine mounts
45 for the tranny mounts

or i could do Vorshlag red 95 urethane engine and tranny mounts for $278 total
189 for the engine mounts
89 for the tranny mounts

opinions/suggestions por favor?

[Finnegan]

There's a thread by someone who installed red poly engine mounts (can't find it, on mobile). Look at that--lots there.

Not aware of any marked diffs between poly. Isolated or bolt through though, that will make a big diff (bolt through will rattle your teeth out). Check the design specs, not just the materials.

With isolated poly in both engine and transmission you'll get a lot more NVH than stock or neoprene. Not an issue if you know that going in.

Give update when done. Thanks.

Just installed Rogue Engineering Performance Engine Mounts and Transmission mounts. As advertised, lots of increase NVH. But it is just at idle, once underway and above 1K RPM, I don't notice it one bit. But at idle, there is a ton of NVH compared to stock, so be ready.

Also installed UUC short shift kit and Vershlag camber kits with AST coilovers at the same time, so all NVH increased, but livable by my terms.

Totally different vehicle with the mods, I'm loving it!

[Finnegan]

It's great to have some feedback on the engine mounts. Thanks.

Original post updated to reflect info on Vibra Technics and cross members. More will be added as data comes in.

Here's an update as have been living with these mods for over 4 months now. Only drawback to the stiffer mounts is the buzz at idle, when at a longer stoplight I just push the throttle to about 1,000 RPM and all is buttery smooth. Asked my non-dealer mechanic if could raise my idle to 1,000 RPM, was told not possible. Dealer tells me maybe, will see at next service interval in about a month. At 1K or more no buzz or shake, very noticable at stock idle speed.

Suspension is great, I wouldn't change a thing with either modification. Ride is as good or better than stock except over sharp edges. Car turns on a dime and offers a dollar in change. Really loving the square setup, maybe should have gone with the 265s instead of the 245, but not beating myself up over it for a street setup. I didn't think I needed them, but now believe I will add upgraded sway bars from Ground Control. Car is handling well, but think this will take it up another notch.

Can't wait to start upgrades in the engine compartment!

I posted this review on AKG Engine and Transmission mounts both, but I did have just the trans mounts on by themselves for a night.

As stated in that thread, these mounts in combination with OEM engine mounts are a terrible idea. And my engine mounts weren't bad at all in terms of wear and tear. NVH was insane. If I were only putting trans mounts on, I would've instantly bought something else. Sorry AKG for the bad words, but it's not a good idea in my experience.
