So the whole point of having a spoiler/bodykit/front air diffuser, technically, is to put downforce on the car so you have traction. But isn't that just like weighing down the car? Like we lighten our cars so they go faster, but then we put front lips and wings on which creates downforce, which is like having extra weight in the car. Unless my logic is flawed somehow. Comments?
No, its not the same. More real weight (like say, cargo in the trunk) has to be accelerated by the engine power output. Downforce from a spoiler only increases traction. Of course, you have to be going pretty fast to get any useful downforce.
