Transmission mount upgrade (KEIN)

The proper material would be Polyelast and there are just limited form factors we can use to make the adaptation. I think Poly in a trans mount will just not hit the right frequencies. We have one that a customer of ours molded but we never tested it. We will see what we can do. Mike

Only the original IS F ones have a shorter service life on the OEM engine mounts..
The only one that fails over time, is the Drivers side / LH mount do to the engine torque upward.
The passenger side / RH mount has no issues of breaking (that I know) at its always being pushed down on.
Anyways around June 2014 the IS F mounts were superseded with new part numbers that are still current and found on all 2015 to 2020 RC F & GS F.
Only time will tell if the newer mounts have the same problems..
If the mounts last 10 years / 100k miles.. I would think they have done their jobs.

I stumbled upon this..

Anyone seen or purchased one? I just ordered mine since it looks overall better then the oem design.

How was the fitment trash? Mine bolted right up no problem. Do you even know the condition of your motor mounts? Seems to me you have a bigger issue with your car if changing out a transmission mount made your car SO LOUD your ears hurt. You installed a mount not open headers so stop exaggerating.

the bracket no longer lined up with the holes. ill try to include pics. and my motor mounts are okay. i barely had any noise before this installation. it really is loud man. i had trouble talking to my passanger during highway driving. do u have IG or something? i can send u some vids. thanks. i exagarrated with the trash fitment. but basically i had to drill the holes bigger to make the bolts go in. the mount was slightly crooked.

I don’t have social media sorry. All you needed to make the support brace to line up was a pry bar and slide the bolt on. If your on stock engine mounts that could possibly make the vibration worse since the oem mounts aren’t stiff by any means. Have you actually checked them? Mine were torn. I’m on solid motor mounts and the kein transmission mount and have slight vibrations at idle but that’s it’s and it’s so insignificant you might not even notice.
anyways, in my cabin it sounds like i have a full straight pipe exhaust eventho i am completely oem.
idk whats up with that.

My exhaust is completely stock. so if it went from close to dead silent on a cruise, to barely hearing my music at level 30, something is defenetely up.
