Suspension Member Structural Requirements

In Simple Terms

F1 suspension parts must be symmetrical and uniform in shape along their entire length, with their center of force staying very close to their structural centerline. This ensures the suspension behaves predictably and safely under the extreme forces experienced during racing.

• Suspension members must have two perpendicular axes of symmetry for balanced performance
• Cross-sectional shape and size must remain constant throughout the entire member length
• The load center must stay within 5mm of the geometric centerline (10mm for steering components)
• Limited exceptions are allowed for adjustments, hydraulic passages, bearings, and measurement instruments
