Over the weekend I installed the poly bushings into the stock lower trans dogbone. Little vibration....an I mean little. Far better shifting and more solid feel.
Just installed the VF Upper Driver and Passenger side poly mounts today. Wow, tons of vibration. Change rattles in cup holder and ash tray and other things in other places. It's not too bad at speed. But at idle and a little above it's a little much. I read all the reviews and all mostly said to stay with the dogbone only for street use and to only use all 3 mounts for racing, etc. I can attest to this. I'm going to run the mounts for now. I'm hoping they loosen up a little. I'm also going to try re-aligning the mounts to see if that will lessen the vibration. Otherwise, if you are really hardcore about getting all your power to the ground....then run these.
