Suspension Fairing Cross-Section Requirements

In Simple Terms

F1 suspension fairings (the covers around the suspension components) must be symmetrical in shape and relatively compact. They have a maximum width of 100mm and can't be too elongated—the longest dimension can't be more than 3.5 times the shortest dimension.

• Suspension fairings must have at least one line of symmetry for aerodynamic consistency
• Overall maximum dimension is limited to 100mm to control size and aerodynamic effects
• Aspect ratio cannot exceed 3.5:1, preventing overly stretched or elongated fairing designs
• No single dimension can be more than 5mm larger than the major axis, maintaining proportional balance
