(click Z4 then trans mounts)
"Gen 2 now shipping
New mechanical retention system on all UUC isolated transmission mounts (red or black) and engine mounts. This design uses a bonded end plate plus an inner plate embedded in the urethane. This inner plate prevents separation of the mount assembly even under excessive force."
To me the wording reads, since the new ones are isolated, the old ones aren't?
