Best Engine Mounts and Transmission Mount Combo

Trying to get your guys input on the best engine and transmission mount combo for a weekend/track 135i. I almost went with the 034 Motorsport but I've been seeing a lot of negative feedback on them.

I went with Turner Motorsports Engine Mounts. They look very well made, no issues since install 15+ months ago and 15k+ miles.

Did you go with the poly 60a or 80a?

60a. Although they say it's similar to OEM feel, there was a noticeable change in my mind. A bit more NVH, and a bit more immediate response/feeling to steering inputs overall.

I did the E46 M3 transmission mounts and found them a great improvement for a dual duty car: https://www.1addicts.com/forums/show...5&postcount=13

I wouldn't recommend my motor mounts, unless you're hardcore about feeling EVERYTHING going on up front. They're AKG 75D poly mounts. Lovely product, and the car feels amazing. It's just really brutal if you aren't moving.

I have E46 M3 trans mounts, and they're pretty good. Shifter doesn't move around so much during cornering, but it did (by itself) add a bit of chatter noise.

Not metal centers, just slightly stiffer rubber and more squared off ends. Slight improvement in shift feel, virtually no difference in NVH.

I have the full metal Engine and transmission mounts from Turner Motorsport in my daily driver and they feel great.

Solid engine, trans, diff and RSBs.


See my last couple posts:

The solid rear diff mounts install was delayed again - should be in by the end of this month.

The solid trans mounts were removed but will go back in, probably mid-April.

Appreciate all the feedback! I went with turner motor mounts and rouge engineering transmission mounts! I have a set off condor speed transmission mounts as well, if anyone would like to buy them off me.

I am running the turner hybrid motor mounts. It’s rough at idle, but once the car gets going the vibration is not really noticeable over OEM mounts. You do pick up a little more engine noise. I ended up setting my idle at 950. If I am stuck at a long traffic light, I’ll put my dct in neutral just to limit the car shaking so much.

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.
