1) Honda, Williams and other teams used those endplates for there sidepods, and I have seen on the forums there has been many explanations, does anybody know the real reason for these endplates and other assorted diagrams because even I am confused on there purpose?
2) What does dirty air mean? What does Clean Air mean?
3) Do teams make new wings for the front and rear for every race?
4) How does a team know they made cosiderable progress to there car, as a whole because each race they bring aerodynamics updates to suit the car for each track? Is there any way to gauge that they made true progress to the car as a whole, would be how far apart they are to the leader in regards to lap times or speed?
