987 Engine mount - new revision changelog?
 

I recently replaced my 987 engine mount after 62k miles. One of the rubber attachment was cracked half way and as soon as I took it for a drive, I noticed it's less hesitant both in acceleration and up-shifting gears.

Both new & old mounts have P/N 987.375.023.02 but I see on Suncoast they have listed 05 revision which supersedes 02 03 and 04. Anybody have any info on what's changed? I understand they change the P/N when they change supplier as well. Thanks.

I got an aftermarket Lemforrder motor mount that was marked (at least on the packaging) 987.375.023.05 (and I just noticed it also lists 987.375.057.02 elsewhere on the box), and as far as I can tell, it looks like yours. (This was just the bushing - I pressed it into the old bracket from my 2001 Boxster).
