Yes, no need to worry.

What poly mounts did you buy? All poly mounts will give you vibration, depending which ones you get determines how much vibration you will feel. Intense is the softed, ZZP is in the middle and w body store has the roughest. I have the ZZP ones and they are great.

its just minor vibrations middle level i would say not sure on brand bought from another member on here cause my stocks had messed up, only more noticable when in drive and i and sit at a light or something holding the brake and turn the wheel it vibrates rough and rpm drops a bit lower

[footballplaya3k]

That's because of your power steering that your rpms drop, that has nothing to do with the mounts, only the vibration does.

Probably doesn't help you've got those monster dong tong wheels on there either.
