I don't know know for sure, but these mounts were used on the 993 (as engine mounts since the engine is in the back of a 911 rather than the transmission) so its something that they had available and already in production.

Yes, there are full rubber mounts and some semi-solid mounts. Both will increase vibration quite a bit. I have the semi-solid mounts on my Boxster but its a race car so NVH (noise, vibration, harshness) isn't a concern.

Do a search and you can find several posts discussing the merits of other mounts and other owners experiences.
