In 2023 there weren't big changes to this system, while SF-24 got an update and this meant a change in internal suspension geometry, as well as shorter and tighter gearbox
This solution was working very well - for about 8-9 races. In Barcelona 2024, Ferrari brought an aero update package that reintroduced the dreaded high-speed bouncing. The problem was believed to be purely aerodynamic in its nature - but it never really is. Bouncing has to be solved tailored aero-mechanical setup solution
Ferrari worked mostly on the aero side and fully cured this issue with Monza 2024 package. Believing they found the right path for rear end floor development, they were fully committed to an already well-defined rear-end suspension solution within the gearbox casing for their 2025 car
We have now reached the point where we can examine the possible causes of rear suspension issues Ferrari is facing - take a breath and we move on 😁
