Rear Wing Bodywork to Tail Bodywork Assembly

Chapter: C3

In Simple Terms

The rear wing and tail section of the car must fit together smoothly with no gaps. Teams are allowed to use small rounded edges (up to 10mm curves) where these parts meet, but everything must be neatly trimmed and aligned.

  • Rear wing and tail bodywork must be precisely fitted together with no misalignment
  • Small fillet radius curves (maximum 10mm) are permitted at intersection points for aerodynamic smoothness
  • All edges must be trimmed neatly to create clean transitions between these components
  • This regulation ensures consistent aerodynamic performance and prevents teams from exploiting gaps for advantage
Official FIA Text
