I have minor pitting of my eshaft as well I do not know what to do. I polished off rust with steel wool and its pretty smooth... not to thread jack but I dont know what to do either. Also if I do decide to switch to the rx8 shaft will I need to change my rear stat gear? I know there has been discussion about using the rx8 shaft but will it be compatible with my s4 n/a without changing the stat gear? Also what exactly do I need to do with the oil passage on the shaft? anything at all?
