Well as far i know the F1 car needs downforce (DF) only in corners, on straights needs a max top speed. This could be achieved by reducing drag. So why doesn't engineeres coustruct such car that in corners rear spring would raise (the air pressure isn't so high on rear wing) and the height of the car would be higher and result of this would be more downforce. On the straights would be air pressure on rear wing higher, rear spring would get shrinked, but only to the level, where drag would be lower and the car wouldn't get fliped. Result of his would be lower drag on straights (higher speed) and higher DF in corners.
I'm sorry for my english, but i'm from Slovenia.
Does anybody knew where is Slovenia?
