Monaco GP
14/77

Ferrari utilised a high-downforce set-up in Monaco, complete with a new forward monkey seat that exposed the frontal element to the airflow and a new flatter rearward monkey seat - both of which work the airflow harder in order that it interacts with the rear wing. The team also used its higher-downforce hooped and slotted T-wing.

A side-by-side comparison of the new and old wing specifications shows the shorter slot (yellow highlight), the more aggressive arc leading to the outwash tunnel (blue arrow), the arched connection at the juncture between the mainplane and neutral section (red arrow) and the new endplate canard (green arrow).

The FIA forced the team to modify the floor slot, as the previously unmounted section of floor at the rear flapped around too violently. A metal support was added at the rear of the slot (arrowed) to increase rigidity.

The revised front wing introduced by the team for the Austrian GP changed the mainplane's profile alongside the central neutral section in order to affect the Y250 vortex differently. In the outboard section, the long slot (left inset) was rescinded, making way for a shorter slot over the top of the revised arc that forms the outwash tunnel. Hung from the endplate another, more complex, canard was added too (arrowed and see also right inset)

An illustration of the SF70H’s upright and brake assembly, with attention paid to the number of drill positions on the brake disc. The maximum configuration used in Singapore featured six drill holes across the face, drilled in a chevron formation in order that they didn’t fatigue the disc when heat was dissipated. Contrary to that, less heat being generated for Monza requires less drill holes (four across the face).
