i apologise if i give u the wrong impression, but it only gives favorable value of downward force when the speed is above a threshold, its doesnt have much fucntion below dat speed but to create unnecessary drag.
i wud post the link where active spoilers such as on those veyrons only activates from a certain speed onwards, but i cant access youtube from the office. can sumbody search for it and post it here? id appreciate it much, tqvm in advance.
u have the exact formula to calculate downforce sir, the thing u need to take into account is the weight of the car, airflow beneath the car, and if the weight of the can be overtaken by the lift value at a certain speed. if this lift < weight, then the car will still be planted on the ground, definitely. u need d extra downforce when weight is about to be outnumbered by the lift value, before this threshold point, that extra downforce generator will only add drag because the downforce value isnt appreciable. dats not taking the ground effect of the vehicle, all this helps but for maximum acceleration u dont need dat additional drag, as to y the veyron doesnt employ the spoiler until its needed.
kuasa dua is square btw, lol (aku pun lupa jap tadi, hahaha)
ground effect will be better if the car is closer to the ground, but not to a point dat appreciable airflow cant flow through. dis reminds me alot to ayrton sena's accident, just a simple problem / mistake but made us lose a legendary racer
