Air doesn't car how fast you are going, it's going to start affecting the moving body as soon as it starts to move. How much it affects it, is roughly a square function, ie 2X the speed you get 4X the downforce. So it is true you get more affect the faster you go, but size of wings, splitter, dive planes, etc., affect how much you get and how soon. If you look at the current FSAE cars, most never see 60mph, but the better teams are running full aero cars.
