Rear Wing Adjuster System

Chapter: C3

In Simple Terms

The rear wing flap can be adjusted by rotating it around a fixed horizontal axis (aligned with the car's width). When the car is in corner mode (high downforce setting), this axis must be hidden inside the rear wing structure and completely invisible when looking at the car from below.

  • The adjustable rear wing flap must be made entirely from approved rear wing profiles
  • The rotation axis must be aligned with the Y-axis (horizontal, side-to-side)
  • In corner mode, the axis must be positioned within the rear wing profiles and fully hidden from below
  • This design ensures the rear wing adjustment mechanism meets technical specifications
Official FIA Text
