Ex-F1 technical director Gary Anderson explains Ferrari’s big suspension upgrade, planned for the Belgian GP
Ferrari has been working on a rear suspension upgrade for their SF-25, which was tested at Fiorano before its anticipated debut at Spa. Due to changes in the 2025 car’s packaging, Ferrari had to adjust the position of the cockpit, fuel tank, and engine, affecting the space for the pull-rod operated rear suspension. The rear damper used by Ferrari seemed insufficient in controlling the rear suspension movement, possibly due to the central rear damper. The central damper is crucial for maintaining rear ride height and avoiding aerodynamic issues. Ferrari also enhanced the anti-lift feature on the rear suspension wishbone to improve stability during braking and cornering. The success of Ferrari’s upgrades will be tested at Spa, a track where both car performance and driver skills make a difference, albeit weather conditions can be unpredictable.
