Default Engine Vibration

Hey Guys

Do you think engine vibrations in the cabin can be caused by bad stock engine mounts? The ones on the side of the engine I mean. I put a solid one in the back of the engine a while back. It increased the vibrations a little but it wasn’t bad. So after a couple months of driving I noticed it has gotten worse. Should I put the other solid ones on?

The vibrations im talking about is not at idle I know you will get that from solid mounts but instead like around 3000 rpms when driving. Let me know your thoughts.

ive noticed a "wabble" type effect also around that range sometimes when i floor it... almost as if the axles are out of balance.

if you havent upgraded your mounts you should... the back one alone wont do IMO. i will i noticed after i did all 3 it decreased that sensation alot... but not 100%.

initially.. @3k is when the car really wakes up... anything below 3k is just a frustrating wait for this ____ing car to move.

It gets better with more mounts because it doesn't have a chance to start a harmonic vibration. It just stays put, in which case it is only noisy at idle like expected. I had all 3 in when turbo and it wasn't that bad at all. Now I'm N/A with the one in the rear still (for now) and it's horrible. My exhaust shakes and everything. The front two are the easy ones to install anyways!
