Do the IE motor and transmission mounts transmit a lot more vibration or noise through the car than oem? Whats the general opinion on these upgrades?

As time went on, the factory developed the car each year, making it faster, more comfortable, and capable of handling at higher speeds.

Yes more noise and vibration.
If you have to ask, you don't need them. -
Obviously theyre going to transmit more noise and vibration. Im just asking how bearable the change is. I put new motor mounts in a year or two ago and one of them has already torn, so I dont want to keep replacing them, Im also doing my clutch soon, so I might as well do the trans mounts at the same time. Im looking for subjective answers not yes or no.

They are for race car use.
Some people use them on the street.
Engine mounts transmit alot moe noise, and added stress to the subframe.
Tranny mounts are horrid on a street car.
fucking n00bs i tell ya...Comment

Bimmer8604 has them on his E30 [the motor mounts] and I shit you not, I don't notice any extra vibration, seriously. They're not as harsh as the world makes them out to be, although the tranny mounts may be since I have never been in a car with themComment

I run the tranny mounts and E12 motor mounts. With the tranny mounts, I didn't so much notice more cabin noise, as I did more vibration through the seat. It's totally a preference thing, personally I think it gives you a more "connected" feeling. Definitely not something you want to do though if it's your DD and have passengers frequently...my car is purely a weekend toy.-Brandon

I have both motor and trans mounts from IE on my car, and while there is some increased vibration, it is not unbearable. If you are a waffleswaffleswaffleswaffleswaffles and can't handle a little vibration (a lot less than having real springs and urethane suspension bushings), then these aren't for you. I had a similar problem, motor mounts would only last one track day before they split in half. The IE units are awesome and have survived two track days already.Comment

I drove someones e30 with the IE motor and tranny mounts and did not notice much more vibration (maybe the clunking driveshaft caused by a bad guibo was hiding the vibration from the poly mounts...).

yea i have th motor mounts. I feel more vibration over on myside of the car than where matt sits in the pass. seat. LOL
Seriously tho, I can feel more vibration, and a bit more through like the steering wheel, and down in the footwell.
Its not that bad, you get used to it. It does sometimes feel a bit harsh, on the longer road trips. After riding in a new 325Cic, my car is like the flinstones car.

If you drive your car hard, then get them. Yes there is more vibration. No it is not as bad as most make it out to be.Comment

FWIW, the vibration will be worse in an M10/m43 compared to a i6, since the 4s will vibrate more by design compared to the relative smoothness of the 6.
In an E36, the UUC red tranny mounts are unnoticable in an M3, but vibrate the seats in an 318is.BEERTECH
