Can you elaborate on how the cutouts could add yaw stability? Does that mean, figuratively speaking, that the "groove" cut into the air flow by the cutout acts sort of like a "shark fin"?

I don't know exactly what they're trying to do with the V cut outs, when birds flap their wings their feathers spread open on the return stroke because it induces less drag, but we're talking about F1 cars not birds. I don't think the cutouts are worth it in my opinion, because yeah they reduce drag, but the downforce penalty is not worth it. Now if it's being used in the hopes of adding more yaw stability at the expense of some downforce fine. However, I would not go that route if it was just to reduce drag.

I heard, from a very good source (who knows a man, who knows a guy on twitter, who once walked past the factory), that they're tilting Alonso's hair for a lower CoG.
Upon turn in, the airflow shifts position on the wing, and tends to pool towards the endplates, on the RB8 the upper flap is shaped in such a way as to account for this shift, in other words that central dip helps stabilize airflow shift by preconditioning the flow to go towards the end plates. Thus when you have a yaw moment the shift is less sudden, and hence slightly more stable downforce. It's also why there are cheese graters on the rear wing endplates. It could be that Ferrari are trying to obtain the same effect but in a different way i.e. using the two v cutouts and also in the hope that it will shed drag, however it doesn't seem worth it to me, but I'm not sure, that's why teams test stuff.bhallg2k wrote:Can you elaborate on how the cutouts could add yaw stability?

It looks to me as though they're just a simple way to effectively reduce the frontal area of the wing to reduce drag without resorting to the wholesale reduction in downforce that would result from a wing with a lower AoA. Ferrari is not the first to go this route, either
RB4
RB5
You can see that Red Bull even employed features with the same intent on the sections of the flap that join the end plate. So, too, did Ferrari on the F2004.
