Cooljay, my motor and tranny mounts were changed in January. I ll admit, the day I changed it, the whole car did seem to shake more than before. I gave it a while for the mounts to settle but I feel like its about the same now in terms of shakiness with the originals. In fact when the originals were removed, they looked alright. I did use Karlyn and febi-bilstein for engine mounts and t mount. My mechanic said aftermarket mounts are generally never as effective as the originals.
