special mention to our brother Johnny DB for sharing the reference on the 997.1 workshop manual. majority of the items there are applicable to the 997.2, but is there actually something similar specifically for the 997.2. someone might be willing to share...
Again Johnny DB - that was a very generous thing to do.. your great man.

 

Good question. I'd love to have the data for my 997.2 Targa 4
