Longitudinal loads transfer?
If I understand correctly, Longitudinal load transfer causes the CoG (center of gravity) of the car to move forward and down on braking and the opposite in accelerating. So during braking there will be more load on the front tires and in accelerating more load on the rear tires.
It can also change the effect on the aerodynamics as the air is passing over, around and under the car. So this is why you need to operate with a stiffer suspension in order to counteract the unwanted movement. Is this correct?
So if this is the top issue for SF23 does anyone know if the concern is under braking, accelerating, at low or high speed, cornering or all of the above?
Well, actually, some "dive" was positive, at least in the past. The front wing came closer to the ground and produced more downforce, which was positive when braking, conversely it increases traction when the rear sinks when accelerating. With the ground effect cars, the relationship has changed and the car must not dive too much either front or rear, otherwise the advantage turns into a disadvantage as it can negatively affect the Venturi tunnels and shift the balance adversely, making the car unstable.
