Article C3.18.14
Rear Wing Skins
Chapter: C3
In Simple Terms
F1 rear wings must be rigid enough that their outer surfaces don't bend more than 2mm when a suction cup applies a pulling force to them. This test ensures wings stay stable and maintain their aerodynamic shape during races, preventing teams from using flexible wings as an unfair advantage.
- Rear wing skins can deflect no more than 2mm under 60N of force applied perpendicular to the wing surface
- A 50mm diameter vacuum cup is used to apply the test force
- Deflection is measured at the outer edge of the cup and compared to the lower wing surface at the same position along the wing
- The measurement point must be at least 300mm away from other reference points to ensure accurate testing
Official FIA Text
Skins of Rear Wing Profiles may deflect no more than 2mm when 60N force applied normal to and away from element. Force applied using vacuum cup of 50mm diameter. Deflection measured at outer diameter of cup and relative to lower wing surface at same X-Station, at least 300mm away.
