It was a small modification already expected previously that made its appearance on the SF-24 at Suzuka: nothing transcendental, for goodness sake, it's just a carbon cover that has been redesigned to direct the flows towards the rear axle in a different way , according to the indications that emerged from the work in the wind tunnel.
In the Ferrari pull rod rear suspension, a small appendix has been added to the upper arm of the multi-link which has only an aerodynamic function. The technicians of the various teams are working with great attention in the area of the corners of the drivetrain, in an attempt to clean up the trail of rear wheel losses.
Finding the most suitable solution means generating vortices that help find efficiency and, therefore, performance, in a very sensitive area of the single-seater. The Scuderia had followed a development line that curved the mini flaps that adorn the brake duct upwards. The goal was to increase local downforce to improve tire behavior.
Red Bull, followed by McLaren and Aston Martin, reversed the concept by orienting the fins with a downward curvature. It seems that the way the flows that touch the brake duct swirl changes. The Scuderia has also found its own line of research which combines flow diverters pointing upwards with those which bend downwards.
The suspension arm with an increased cord helps to improve the final result: it is not a major change, but it is certainly useful in making the red car competitive on a track that, at least on paper, must have been difficult for the Cavallino.
Judging from free practice, however, the SF-24 seems to be the only car capable of keeping up with the Red Bulls and if the cold that greeted the Circus in Suzuka continues, Ferrari could benefit from it, given that it seemed less sensitive to the graining of the same RB20 which remains the big favourite.
