Just wondering how much differnece you feel at idle with the poly mounts? I haven't really driven my car alot since I put the energy suspension motor mounts and tranny mount on, but I have been trying to figure out why my idle doesn't feel as smooth as it used to. The car has just had a full tune-up including fuel filter pcv valve and all of the ignition parts. I know the 5.0 isn't the smoothest running engine in the world so I am just wondering if it is the result of the stiffer mounts.

Good upgrade if you're old mounts are bad.
