Installed poly motor mounts along with my tubular k member setup and it seems like i expereince some noticable vibration at idle but it does go away once u start driving. Should there be a large vibration difference between stock rubber style mounts and the poly? It just seems more than i expected.

No one is running polys?

I haven't noticed a difference. Do you think the k-member is worth the $? Getting ready to do some suspension work and would like to go with coilovers / tubular K.

Normal, you'll get used to it.

The poly will vibrate more as you are feeling the vibrations from the motor sense you switched to a poly mount. Plus side to the poly is that since it is a harder rubber you transfer a little more power since the motor is held in tighter and they last much longer than OEM mounts.

You installed motor mounts with isolators made of a much "stiffer" material than the OEM rubber isolated mounts--what did you expect?

I did expect more engine vibration, but the extent to the vibration was extreme, but after futher inspection one of the primaries on the newly installed long tubes was laying agaist the subframe in a spot, the problem was remedied and the extreme vibration is gone and it now feels more reasonable. I would recommend the QA1 tubular k and a-arms, I had zero problems with the installation and it bolted right up no issues.
