Suspension Member Attachment Strength

In Simple Terms

F1 teams must prove their car's suspension parts that attach to the main safety structure (behind a certain point on the chassis) can safely handle 25% more force than they're designed to withstand without breaking. This ensures the suspension won't catastrophically fail and damage the protective survival cell in a crash.

• Applies only to suspension attachments located behind the XC=-1580 position on the chassis
• Teams must provide engineering calculations demonstrating safety margins
• The suspension must withstand 1.25 times its normal compressive failure load without damaging the survival cell
• This is a safety requirement to protect the driver in high-impact collisions
