They can make minor changes to front wing when in part ferme and during pit stops, but allowing changes during pit stops in a management game is ridiculous and as I and others have said makes zero difference since everyone could do it.
I also believe there is an exemption irl if weather conditions are such that not changing may cause serious accidents, but since this is a game it isn’t relevant.
EDIT: just read an article dated today that states FIA is going to ban changes to cars while in parc feme
Rear wing also as seen by RB lately to adjust balance for a harder compound. Of course there are limits as larger changes need a different wing.
If everything in a manager game would be ridiculous that everyone can do then nothing of this game would remain. Also what FIA does is only of minor interest as iGP has its own goals and rules to achieve them.
That said in the game we currently have there is little point to it. The setup system needs to be ramped up quite a bit and different compounds, fuel weights, temperatures and variables like that need to influence to make setup rather a compromise than the set in stone value as of now. Currently there's only weather and I'm not sure at all if the setup actually changes if it starts to rain or determined once by conditions at start. Last time I tried stuff it rather looked like it's the latter, however that was right after 3D so things were a bit uncertain all around and slightly messy in general.
