for the wing guy....yes you would make the speed, but not as quick......the high wing/downforce setting allows you to manouvre corners at high speeds by assisting with the grip the tyres have on the road with the assistance of down-force.......if you adjust the settings and drive (at lowest and then at highest) you will notice a difference in the rate of acceleration in 5th and 6th gears.........The intention with the wash, aside from the shiny looks, is a slight, slight difference in top speed on a long long straight due to less co-efficient drag.,.....this would help if the two cars are almost evenly matched and that extra mile or two per hr would come in handy
