That's what I tried to say the other day, not as eloquently, but I tried.Henk_v wrote: ↑Mon Jun 27, 2022 7:50 pm"Rake" as I understand it, is using suspention to elevate the entire back of a flat floor design rule to have said flat floor work as a diffuser, getting some downforce with low drag. It is a workaround to a rule and not a design goal. It made flat floor cars pointy, because it lowered the front wing in a car rule in which a lower wing was better.
As the flat floor is no longer there and most of the floor is now intricately designed, rake is not really relevant is it? It could only apply to the plank area. And even then, would the floor edge be a means of judging any rake of the plank? Im not familiar with the exact rules on the floor edge positioning relative to the plank, but maybe they are not in the same plane at all.
You couldn't touch the floor back then, while today, there is all kind of space that they can play with in there, from a rule perspective.
Also, raising the floor drops the nose and front wing. At the very least that gonna create turbulence to some of the air feeding into the floor, worst case reduction of the air available to the floor. Wing regs are such that make it very difficult to do much more that create df at the wing.
