The winglets on the rear wheels, do they move with the alignment of the wheel? If you toe in at the rear, and if the entire aero assembly moves with the wheel alignment, then you are moving the leading edge closer to the diffuser. With toe out, you would be moving the trailing edge closer to the diffuser.

With toe out, you also create stronger jetting vortices from the tire. The wheel furniture, and the alignment of the wheel works together to strengthen the airflow traveling along the side of the diffuser. The closer the wheel winglet is to the car body, the more that area can function like a nozzle.

They would have to be mounted to the hub and move the same direction as the wheel as you say, or else any toe or camber adjustments with sidewalk flex would break them off. Correct me if I’m wrong…

Did everyone else had problems with porpoising? Is there footage of others?
I'm guessing those will be the fastest cars that successfully avoided the problem in their design. The others will need to resort to workarounds.

Rumour is every team has it. Some sources say Mercedes have it worst others Alpine or Red Bull. I think it will be the cars with more aggressive underbodies suffering the worst. I had not expected this though - maybe naive of me to think the simulation tools would catch it.

Joylon Palmer says Mclaren is the only team not suffering porpoising.

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

But also that they're running their DRS on every lap - so reducing the overall load.

Kyle’s RedBull analysis is up and it’s rather fascinating!

Teams are lobbying the FIA to bring back inerters to control porpoising.

Not sure if true, but I really didn’t understand banning these. I can find two dozen + cars at any serious amateur race weekend with them.

Hydraulic inerters? I don't see too much outside of the top end of motorsports using them, they can be tricky to tune.

I ran one for a while but setting up for every event was hit or miss sometimes, they could cause some odd load fluctuations if you didn't nail it.

You see them some of the higher end Formula and Sports Racer classes. Benefit of a prep shop is they have data across all the cars, but yes, it would be tough for an individual effort.

Also popular on the rear of Pro Stock and Pro Mod drag cars, but that application makes a lot of sense for them.
