Turner engine mounts - anyone else found them unfit for street use?

[poss]

I just Installed Turner's 70A Engine Mounts (see https://www.turnermotorsport.com/p-553269-turner-motorsport-polyurethane-engine-mounts-70a/ ) described as:

These mounts get you as close as possible to solid mount race performance without all of the excessive NVH (Noise, Vibration, and Harshness), allowing you to perform all the time yet still maintain daily driving comfort.
- 70A (blue) - Tailored for a performance oriented daily driver with only slight increase in NVH at idle and stock-like driving experience at cruising RPM

but the NVH increase was significant. The whole car vibrates like crazy at idle - can't even see out of rear view mirror. Unusable for street in my experience. Gonna have to pull them out and go back to OEM

Anyone else had this issue?

Is your idle RPM stock?

Is your idle RPM stock?

Around 750 RPM - anything below 1000 RPM produces a very unpleasant sympathetic vibration throughout the vehicle

Above 1000RPM NVH is acceptable/pretty much like stock

Weird, you would think a sympathetic vibration would be pleasant.
On a side note maybe just program the idle to be a little higher and see if that makes it tolerable.

Perhaps the vibration is pleasant to the car, but probably not as it rattles the shit out of it.

The vibration goes back to near stock at 1200 RPM. I am not going to set the idle that high. I also lost the use of my aftermarket strut brace as the mounts are apparently higher than stock.

If I don't get a refund from ECS feel free to make me an offer :-)

My impression from discussions on here is that raising the idle to a minimum of 1000 rpm is necessary to run mounts like these. Unless you want your fillings to rattle out.

poss, are you running a non-OEM flywheel?

Poly will always be "unfit" for engine or tranny mounts. And other places...

My impression is that ECS's claim that the increase in NVH at idle is "slight' is entirely misleading based on my own experience

Why didn't you tell me this before!

not to my knowledge

UPDATE: Turner's engine mounts turn out to be a bit higher than stock, and this caused the engine height to be raised enough for the fuel rail to touch the strut brace. Removed the brace and this reduced idle vibration somewhat, but not down to what either I or my mechanic call 'slight'.

The mounts weren't all bad - they certainly offered a minor improvement in responsiveness and the SMG seemed to benefit from them as gear changes became virtually faultless - but I swapped them out for new stock rubber mounts because the idle vibes were intolerable for me. Now back to zero vibration and strut brace back in place.

... and ECS has refunded me - but for the wrong item DOH!.
