Outboard Floor Flexibility

In Simple Terms

F1 cars have flexible floor edges, but they can't bend more than 8mm downward when 500 Newtons (about 50kg) of force is applied to each side. Teams test this by gradually loading weights and measuring the deflection to ensure the floor stays within limits.

• The floor's outer edges can deflect maximum 8mm vertically (Z direction) under load
• Testing applies 500N force per side in two stages: first 250N, then full 500N
• Deflection is measured from the rear of the car using specific support points as reference
• This rule prevents teams from creating excessively flexible floors that could gain unfair aerodynamic advantages
