Polyurethane Filled Motor Mounts, V-V-I-I-B-B-R-R-A-A-T-I-O-N Options

There has been a gross understatement concerning the amount of vibration that is transfered to the cabin when using polyurethane motor mounts.

That is all.

i have the ones from kirk. i noticed some slight steering wheel vibration for the first few weeks after installing them as well as a few slight noises from the front bumper. most that stuff smoothed out after a few weeks of driving. besides that, its nothing horrible.

The vibration for me on the Kirk mounts isn't so bad once the engine/bay is all nice and warm.. but on a cold morning ... the vibration is horrible.. it's so annoying.. everything buzz's.. I'm only using rear mount inserts too... I bet if I just had the inserts on the front the vibration wouldn't be soo bad.. but I was trying to get the back of the motor to stop flopping around so the exhaust would stop smacking the rear cross member.

^^^same here. Initially I installed both the front and rear kirk's inserts. The vibration was not all that bad while driving. But it was a little too much for me at idle (buzzing interior panels), so I took the front one off and left the rear one in. Now the vibration is very minimal, besides I can't really tell the difference btn using both inserts and just the rear inserts.

Wouldn't having only one insert on/in put more stress on the corresponding(front-back, left-right) stock mount? Just wondering if that's gonna cause problems...

Yes only having one mount that is polyurethane will put more stress on the other non poly mounts. It will likely wear the stock mount out faster. I would recommend evening it out or go to stock.
