I recently picked up the Medieval rear motor mount to my GF's Speed 3.

My roomate and I tackled it today. It was very straight forward and took about 10 minutes from start to finish. Vibrations are next to nothing. Feels like stock at idle, but holds the TQ very well. For $109 it was a steal.
Only complaint would be that the bolt was very tight going in the mount.
