Having spent its tokens at the rear of their 2021 Formula 1 car, Scuderia Ferrari was not able to make any structural changes to their nose. Yet in an effort to improve flow around the main body and incorporate a more prominent cape the Maranello team narrowed the front wing mounting pillars to free up the space needed.

The SF21’s ‘S’-duct outlet was also framed by four winglets either side of the chassis to help divert the surrounding airflow.
Ferarri SF21 floor
Having tested a 2021-specification floor during Free Practice sessions in the previous season, the Italian side initially implemented a tapered floor solution, much like what the rules had intended.
This included a trio of outwash winglets midway along the tapers length, a collection of winglets on the outer edge of the floor just before the tyre and a horizontal blade connecting them with the strake inboard of them. It also added a trio of fins beside the rear tyre to help mitigate any additional turbulence that might be caused by the regulation and tyre changes (inset, red arrow).
The team moved to the Z-shaped floor cutout in Imola, utilising an angled strake on the forward joint in order to help promote the desired aerodynamic effect.

Ferrari followed this up by making changes to the number and design of the fins mounted on the rear outer edge of the floor. Ferrari SF21 rear wing Spanish Grand Prix:
The high downforce wing used by the team featured elements that took up a significant percentage of the allowable box region and a double element T-Wing. Ferrari SF21 rear wing qualification and race, Azerbaijan Grand Prix:
The lower downforce offering as a comparison with no T-Wing.
The medium downforce wing sported a spoon-shaped mainplane in order to create more downforce in the central section of the wing, whilst reducing the drag created at the wing tips.
Ferrari also had a few front wing specifications at their disposal, with notable differences to the shape of the footplate and the position of the adjuster, with the latter dictating how much of the wingspan is adjusted.
The trio of outwash winglets that had featured on the tapered floor solution made a return later in the season, applied this time to the Z-shaped floor. Also note how the lower portion of the rear wing endplate was cut back, where previously it had a tail section.
Ferrari spent its development tokens for the 2021 season on their gearbox carrier in order to extract more performance.

Ferrari uses a brake drum heater when the car is in the garage in order that all of the components are brought up to the optimum temperature.
The more open version of the Ferrari brake duct designs includes a wedge-shaped strake to help define the airflows path in the bypass section.
