As an engineer, the moving rear wing, or DRS, reduces drag for higher straight-line speed, while the air brake—what we call the rear wing's maximum angle—creates massive downforce and drag to slow the car rapidly. But this sterile explanation forgets the feeling in the chassis. I say this because in my shop, a farmer once explained his old fan's wobble not by the loose blade, but by the whole room shaking—the entire system matters. So at 200 km/h, these devices don't just push air; they change the entire conversation between the car and the road.
