01 - BIG IDEA

Total downforce is not the whole story

A car with lots of downforce can still feel terrible if the load is in the wrong place.

The front wing, floor and rear wing all add downforce at different locations. The driver feels the relationship between front grip and rear grip, not just the total number.

02 - TWO WAYS BALANCE GOES WRONG

Understeer and oversteer

Understeer means the front refuses to turn in and the car runs wide. Oversteer means the rear rotates more than intended and the back feels loose.

03 - CENTER OF PRESSURE

One point to summarise all aero load

The center of pressure is the point where you can imagine all the car's downforce acting together. If it shifts forward, the car becomes more front-biased. If it shifts rearward, it becomes more rear-biased.

Center of pressure combining front wing, floor and rear wing loads — The actual downforce is spread out, but the center of pressure helps us reason about the whole car.

04 - SHIFTING BALANCE

Front wing and rear wing are connected

Increasing front wing load moves balance forward. Increasing rear wing load moves balance rearward. Engineers think about both together because changing one changes the car's handling relationship.

Aero balance slider with front and rear wing — Front and rear aero settings are not separate decisions; they are a pair.

Balance = front downforce versus rear downforceNOT JUST TOTAL DOWNFORCE

05 - TRACK TYPE

Different corners want different balance

A slow sharp corner can reward more front bite. A fast sweeping corner often wants neutral or rear-biased stability. This is why setup is never one-size-fits-all.

Slow sharp corner and fast sweeping corner aero balance — The “right” balance depends on speed, corner shape and what the driver needs.

01Too front-heavy

Sharp response, but rear can feel nervous.

02Too rear-heavy

Stable rear, but front can push wide.

03Good balance

Predictable grip where the driver needs it.
