I tried to find a few things on rear engine mounts but just couldn't find it. Anyways I finally decided to go with the VF enginering rear motor mount. I had heard that you get some vibration and what not but I was wondering since I don't have a tune to adjust the idle is the vibration really that bad?? Or is the positive result just outway the negative? Because I was really hesitant about it for awhile but I figured what the heck, thanks in advance for the feedback.
