Engine and Transmission mounts...what did you upgrade to and why?

Looking at getting new engine mounts and transmission mounts. Not ready to go solid...this car still gets driven on the street quite a bit, but figure I should upgrade beyond factory if I am doing it. TIA!

I ended up buying Revshift engine mounts. Have yet to install.

Installed Rogue transmission mounts and found them to be perfect for a street car. No real NVH increase, but definite improvement in shift quality.

I'm thinking about doing the RE ones. I have E46 M3 mounts now but I want to tighten up the transmission even more after driving a friend's Z4 M, not sure I'll get it quite that good though lol.

AKG 90A motor mounts and trans mounts. Necessary for a chassis mounted shifter. Definitely feel them. Beautiful pieces and they work.

The shiftier carrier itself also has a lot of play in it. Consider getting delrin bushings for the two front bushings and figuring out a way to stiffen the rear mount. I filled mine with liquid poly which usually doesn't last long.

can you explain a little more? What's the shifter carrier? How difficult to install bushings?

Part number 2 can be replaced with something like this: https://www.turnermotorsport.com/p-3...it-ultra-oval/
Or this: https://www.ecstuning.com/b-ecs-part...it/2511-002~3/

Part number 5 doesn't have any "upgrade" part as far as I know but it is very soft and has a lot of play in it. There is a groove through the middle that almost makes the bushings hollow similar to the rear sub-frame bushings. I filled that groove with Poly to stiffen the bushing and it made a pretty noticeable difference.

Would the driveshaft need to be removed for this install?

How is the install? I love these low cost bushing upgrades

It's doable with small hands. You can bend the heat shield back and reach up behind the transmission. Look at the install instructions for a DSSR if you want to get an idea of what you would be looking at.

If you undo the transmission mounts you can pull the trans down to gain more room. The two bolts that hold that rear bushing in are actually a big pain. I had to use a wrench with very small turns since a socket wouldn't fit over the top of the bolt. It is doable though. It will probably be blind. Once you undo the rear bushing the shifter carrier will be free to droop and you can slide the bushing off.

Reviving this thread as I deferred doing this last year but ECS is having a sale so...I'll ask the question a different way...is there any real performance reason to get stiffer mounts if you have a DCT? Car is almost at 100K so it's about time to replace motor and trans mounts anyway. Just need to decide stock or aftermarket.

Manual 128i, but I did E46 M3 trans mounts and AKG engine mounts. Thinking back, I’d do 034Motorsports engine mounts or new OEM ones, these AKG ones are brutal in the best way possible.

Here's my update in the M3 forum:

I haven't installed the solid diff mounts yet because that was going to be an involved process but will install them in a few months. I don't expect much additional NVH compared to the current rear end setup.

I installed the solid engine and trans mounts and immediately noticed increased NVH. Since there were a lot of other changes made at the same time, I decided to remove just the trans mounts and revert back to OE trans mounts - NVH gone. This was just to ensure it was the trans mounts and not something else that contributed to the increased NVH. I didn't mind the increased NVH so the plan will be to re-install the solid trans mounts at the end of the year.

The solid engine mounts have been in for over six months and I have no complaints at all with them. Maybe a very slight (to me) increase in NVH but nothing at all that concerns me.

DO NOT DO 034 MOUNTS. Mine came apart after maybe 5000 miles.

For my swap I'm doing the turner solid mounts.

034 mounts seem like a great option but reading your experience and a few others is a big red flag. How did they come apart? Did 034 make it right? How long ago did you buy the mounts and install them?

I wonder if they have revised the design at all to address these issues.

I did the softer of the two options for the Turner Engine Mounts. Did increase NVH a bit, livable for sure, but it's not the ultra smooth GT car that some people may be after. Specifically at idle the car vibrates a bit more.

They were installed probably a year ago by a local shop - at the time I didn't have a garage or equipment to do it myself.

I discovered the issue when I pulled the engine and one of the mounts came out in two pieces (the lower plastic disc had separated from the rest of the mount housing.)

I didn't bother going back to get it fixed/replaced because the shop is now an hour away...and my car currently has no engine.

Further update:

I finally had the solid diff mounts installed. No noticeable increase in NVH but I already had a solid diff brace installed, which at the time did make diff whine noticeable, which is something I've learned to live with and ignore.

Summary of installed solid mounts:
  • Sold rear subframe bushes (RSB) - no increase in NVH.
  • Solid diff mounts - no noticeable increase in NVH with an already installed sold diff brace. There would likely be some increased diff whine without a sold diff brace but would be bearable.
  • Solid engine mounts - very minor (easily bearable) increase to NVH. Becomes unnoticeable.
  • Solid trans mounts - introduces considerable NVH but just bearable.
YMMV depending on your tolerance level for NVH.
