F1MathGuru thank you very much !
Here an excerpt from an Italian technical site:
THE DEPORTANCE: The rear wing width increases on the rear side, affecting a greater amount of flow. On the front, a similar fate awaits the profiles of the front wing.
In this sense, it is logical to foresee an increase in deportation.
Despite the smaller number of deviating wings around the wing profile, the deporting device placed in front of the car will be able to develop an adequate level of aerodynamic load. It will probably be even higher than recorded in 2018. The performance of the machines should not be affected compared to those measured during the season just ended.
Moreover, a greater horizontal extension provided for the frontal wing profile would shift the total aerodynamic load towards the front, further loading the steering wheels. All this would play to the advantage of the car's performance in terms of agility and maneuverability.No problem for the balance, because, with a larger wings also at the rear, even the engine axis would increase the load towards the ground, balancing the car again,
which would take a boost to the ground higher.
The profiles will have more room to extend and this, in theory,
in favor of aerodynamic downforce. A much simpler front wing in terms of secondary aerodynamic components, which until 2018 helped the flow to bypass the car body, will take place on the cars in 2019. Do not think, however, that this could cause a reduction in downforce.
The only disadvantage, therefore, could be a greater resistance to progress.
