Legality Setup

Chapter: C10

In Simple Terms

Each F1 team must set up their car's front and rear suspension geometry in a specific way, with the wheels positioned at precise angles and heights relative to the car's body. The front wheels must be angled at -3 degrees and the rear at -1 degree to ensure consistency and fairness across all teams.

  • Teams must establish a unique suspension setup for both front and rear axles
  • The YW axis must be parallel to the X=0 plane (perpendicular to the car's centerline)
  • Front axle wheels must subtend -3 degrees to the Z=0 plane; rear axle wheels must subtend -1 degree
  • Wheel coordinate origins must stay within specified Z-axis height ranges
