number 2 - I'm not sure if it's a track rod (like you mention it doesn't have any possibility of change the trackrod length) or a wishbone cause Ferrari have already used 2 element wishbones, instead of a complete wishbone.
I think that it's real PUSH for toe In 'cause inside it has wire connecting to wheel in one side, and other side wire must connect to gearbox. It'll be strange to do it using main PUSH. In this case yoг wire must be at the upper side of gearbox and must be connect to some holder near rocker and other moving parts....
It's very easy to produce wire inside Toe in Push whithout problem that you have in other case.
(But How guys change leight????? )
