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
