I wonder if they could use the different thermal properties of layered metals to introduce a bend, bend when hot, flattern when cool

Just for absolute clarity, when is the first race where the FIA “clampdown” (for lack of a better word) on the floor rules kicks in?

This is where there is suspicion that Red Bull and Ferrari have flexing floors that could be aiding performance?

At Spa.
The impossible often has a kind of integrity which the merely improbable lacks.

For trying to introduce it initially in Canada, they are certainly in no rush now. Waiting till August...

Piola reports changes to floor limit (bottom minimal height will be raised), addition of diffuser vane and a limitation to diffuser ramp angle - all to counter bouncing by design.

And they call it a stall. A STALL!

I saw a 25mm raising of the floor edge and a change in diffuser ramp. We'll know for real at the next WMSC meeting when they publish the rules. Then 6 months after that when the teams have moaned enough to change them again.

How does the vane counter bouncing? :?:

Maybe it helps to keep the flow attached or rather more directed (acting as a flow conditioner) at more extreme rake angles. And prevent diffuser stall ?

Pure speculation until a CFD Or WT model is seen

Couldn't they mandate a 25mm skirt on the floor edge to solve some of this?

How is that supposed to be useful?

I think that the 25mm step edge is targeted at those teams that are running with the floor outer edges in contact (particularly the rear half of it) with the track AND getting rid of the ‘skates’ that most teams are now running (hats off for seeing that the floor-edge-wing could be appropriated legally for such a device!)
The more that I learn, the more I appreciate how much more there is to know….

Not sure, to be honest. It might produce a consistent vortex, providing the suction to prevent diffuser stall when the car gets too low. I think raising the outer edges will be the most important thing. Having them higher (and stiffer, but that's up to teams to decide how) will prevent excess mechanical floor sealing, which can lead to bouncing in corners.

I think the vane is more about securing a more consistent and straightened flow through the tunnels, preventing turbulence when bottoming out. But just a guess

Not to nitpick here, but what do you mean by "preventing turbulence" - did you mean flow separation? Also, the flow upstream of the diffuser is not "turbulence free"

The strakes or vanes produce a vortex which convects downstream and they inherently add more turbulence.
