Ferrari SF-26

The flow sturctures are too numerous to say the wing is doing only outwashing or inwashing. One thing is for sure: the designers are putting elements where he needs them to get more ideal downstream conditions. The footplate strakes in this case are inboard butt this roll of vortices will clearly move behind the front tyre and outward to protect the floor (perhaps the claws?) from wheel wake.

Air naturally tends to inwash due to Front Wing suction and Front Wheels pressure. Those strakes actually decrease the inwash. If air inwashes at 20°, those strakes are placed at roughly 15°.

Not sure. Ferrari is one of the joy team to have a front wing loaded in the external part with the flaps. So the underside of the flaps tend to outwash the air. Combining the effect of the strakes (which are inwashing) think they want to generate a vortex. That vortex maybe is handled by the revised sidepods, that in the underside can welcome a different flow topology
But that’s only my opinion

1 - A loaded wing means even more suction, underneath. The air gets sucked inward under the footplate.
2 - The strakes are outwashing relative to the airflow. Of course they tend inwards relative to the car center line, but it's the airflow direction that matters. In other words, thanks to those strakes, air inwashes less.

Bingo.
Generally most of us tend to view the 'aero-map' of a car when it's pointing straight (yaw=0). Actually the 'operation' of downforce devices is in the corners when yaw=non-zero. So if we look at these strakes w.r.t the inner tyre in a corner, they will generate vortices that will block/steer the tyre squirt away from the front tea-tray/bib area.

I’m so curious how those two layer daggers work. Is it just like a multi-element wing in that it can get better airflow attachment with a higher AOA by stacking elements?

I think so, reducing airflow separation and turbulence at the floor's leading edge would definitely be a good thing. McLaren seem to be following Ferrari in this. OTOH Red Bull and Audi in particular have much more sculpted claws that will turn the airflow much harder, so two different philosophies in this area seem to be emerging.

New wheels for better heat management. Apparently just the rears, though I’m not certain on that.

Is the Monaco wheel the previous spec and used at all previous races? Trying to figure out if the Barcelona spec is more a circuit type of upgrade to be used at faster tracks.

The Barcelona spec (image Brahmal posted above) does look different to what theyve ran at previous circuits imo. these are the best images i could find of it, left is China, right is Australia to compare it to the image Brahmal posted above. From the way AR and The-Race are talking about it, it doesnt seem like its just a circuit specific upgrade as the fia doesnt allow them to bring rims for specific circuits.

All four wheels according to The Race.

Looking back at #FerrariF1's massive update from the last BarcelonaGP! Here is a closer look at the redesigned front floor leading edge profiles and claws, showing some clear changes (arrows).

I’ve always wondered how long the second layer of the daggers was. I had no clue it stretches all the way down. It must surely work like a two element wing.
