== Ride Height Sensitivity and Platform Control ==

2022–2025 F1 cars exploit floor-generated downforce via venturi tunnels. Platform control is critical for diffuser efficiency and vortex sealing.

Static targets:
* Front ride height: 25–30 mm  
* Rear ride height: 45–55 mm  
* Rake: 1.5° (Red Bull), <1.0° (Mercedes)

Aero model output (CFD correlation):

{| class="wikitable"
! Change !! Aero Impact
|-
| +1 mm front ride height || –0.8% downforce, +1.4% balance rearward
|-
| +1° pitch forward || –2.2% aero balance forward, +3% yaw sensitivity
|-
| +2 mm heave stroke mid-corner || diffuser stall risk ↑ 18%
|}

Teams simulate with pitch-sweep and heave oscillation modes under fuel load variation and rear wing DRS closure. 1 mm pitch instability can cause >0.1s/lap penalty on aero-sensitive tracks (e.g., Silverstone).
