Ferrari SF-25

[FDD]

Fake news, as has become usual from them

What exactly, filming day?

No, stuff from Arcari and FUAT about poor gains from rear suspension. Click bait

Lately I found out that tunnel/simulator/seven post shaker rig correlation, stated by Arcari is stupid, that is to say that everything that he said regarding the new rear suspension performance is a non sense.

Article is copy-paste from FUNO or the other way around.
The main purpose of the filming day is shake down and initial feel of the pilots.
AFAIK any data collecting is prohibited, if not all then in large extent for sure.
Would be excellent to see some good photos from the rear in which I doubt.
Pretty sure that we have to wait earliest until Thursday (Spa) before we see some at least decent photos.

Does anybody with a keen eye spot anything different?

It looks identical to me. But then again, I guess any changes were likely fundamental, but minimal visually.

Not great pictures for spotting changes, but I don’t think it will look that much different externally.

Not as extreme as the Mercedes solution and Ferrari is focusing on the car to reduce lift through the high speed while also maintaining lateral movement of the anti-roll bars to operate as intended.

Some thoughts depicted from the Italian media:

"The new upper leg was mounted forward and downwards in order to increase the anti-squat and also to modify the car`s roll center more to the inner car chassis. The issue was that the car had a bigger roll movement in the high-speed corners, meaning the ride height wasn`t neutral, thus generating inconsistent DF levels from the floor. The roll center is in conjunction with the CoG, and the question is why they didn`t design a suspension with a bigger anti-dive and anti-squat effect. The answer is that adopting this design would lower the car`s CoG. But the SF25 car has a lower CoG (due to all the radiating masses being lower) than the SF24, and they want to avoid the issues VER had in 2023 and Macca last year with the front tyres warm up in qualy and the driver's sensitivity to the car. Thus, adopting a conservative anti-dive and anti-squat design was affecting the car`s roll in the high-speed corners, knowing that CoG is closely related to the car`s roll center ...

In addition, in order to cure the roll issue, the lower rear leg was moved slightly forward, and the carbon shrouds around the suspension arms were reprofiled for a better airflow towards the diffuser. Another issue with the car rolling was that lowering it too much on one side, the vortex generated wasn`t powerful enough in order to seal the floor against the exterior air infiltration under it ...

This car design error was due to the lack of knowledge and know-how of an entirely new project around the adaptation of the new pull-road front suspension, something that wasn`t the case for the Red Bull and particularly for the Macca team ...

Ferrari brought a subtle yet intriguing change to the SF-25 during their Mugello filming day: a tweak to the rear suspension geometry that could have big implications for aero balance and ride stability. The update seems to mirror something Mercedes introduced earlier this season. If you're into the details of anti-lift, anti-squat, and suspension-floor interaction, here's a full breakdown worth checking out:

In the pictures above, you show LEC's car with both the old and new suspension. However, each time he ran with the rear wing in Monza configuration, it seems ...

From there, the following questions can be asked:

1. Which driver and when did the tests with the V-shaped rear wing take place, as we could see in other pictures?
2. Who worked on the setup for Spa (possibly also Monza, given the very thin rear wing), bearing in mind that Spa will be a Sprint race, and so the drivers will only have an hour in FP1 to set up their cars?
3. At Spa in FP1, will the setup work be split between the drivers? Meaning one of them will work on the race setup and the other on the Sprint race? Or will both drivers have the same program, including both the setup for the Sprint race and the race on Sunday, as well as the qualifying for the Sprint race? In my opinion, given the very short time allocated to set up the car, I think they will just concentrate on the setups for the Sprint race and the race itself, and after the Sprint race, they will make the appropriate changes for both qualifying and the race on Sunday ...

Hi, that is only a photographic reconstruction of how it changed, like the drawings present on this forum, no more and no less. It is not the actual car that ran.
