Accordingly to our owner's manual (p. 198), Optimoly TA paste is the ONLY paste to use to thinly grease the tabs onto which our wheels mount. Looks to be just ordinary aluminum anti-seize, but then....

Researched here and elsewhere and the paste was called Castrol Optimol Paste TA until 2015 when the name was changed to Castrol Molub-Alloy Paste TA. Some confusion over on the 997 forum (https://rennlist.com/forums/997-foru...mol-paste.html), but if you read to the end of that thread you will see my conclusion that it's the same stuff.

Just FYI, and happy to have anyone correct me if I got this wrong!

 

Can you help me understand what tabs means?

 

The bits that stick out from the hub on which the wheel is hung when installing the wheel. The hub, but they are tabs. Picture on the page noted in the owner's manual.
