A breakdown view of the SF70H’s sidepods and the bodywork that surrounds it. The removal of the forward flow conditioning bodywork exposes more internal detail including the two cooling inlets and the movement of the upper crash structure spar to a lower, more forward position (lower arrow).

The slot on the edge of the SF70H’s floor had a metal support mounted in the forwardmost section (circled) to improve rigidity, after concerns were raised by other teams over the floor's flexibility.

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.

Ferrari began its weekend with a more conventional rear wing assembly and a perforated Gurney trim above the engine cover outlet - but come qualifying and the race the team switched to a spoon-style rear wing and ditched the perforated Gurney (insets).

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 In the outboard section, the long slot (left inset) was rescinded, making way for a shorter slot over the top of the revised arc that forms the outwash tunnel.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)

Ferrari followed Mercedes' example by adding a longitudinal flap on the edge of the L-shaped floor, just ahead of the rear tyre (highlighted in yellow). Note the curvature of the floor below (dotted line), which mirrors the shape of the flap.

Among the changes are the spoon shaping being discarded for a more conventional short chord, a lower angle of attack, only one centreline slot gap separator and V groove (black arrow) and a change back to a more conventional set of endplate louvres (highlighted in yellow)

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).

Kimi Raikkonen's SF70H is stripped down on the grid as the team tries to resolve an issue with the power unit. Note how the power unit has been enclosed in order to improve airflow through the car. The louvred panel above the radiator is also notable as it improves its efficiency.
