Front Wheel Steering Angle Range

Chapter: C10

In Simple Terms

F1 cars must be able to turn their front wheels to specific angles: at least 23 degrees inward (toe-in) and 21 degrees outward. This ensures all cars have minimum steering capability for fair competition and safety.

  • Front wheels must achieve a minimum inward turn of +23 degrees
  • Front wheels must achieve a minimum outward turn of -21 degrees
  • This is measured at the car's 'Legality Setup' configuration
  • The measurement is taken relative to the car's centerline (X-plane)
Official FIA Text

It must be possible to achieve minimum angle of +23 degrees / -21 degrees (positive toe in) between principal axis of front wheel and X-plane at Legality Setup.
