Article C4.3.3
Ballast Ahead of XA=0
Chapter: C4
In Simple Terms
F1 cars must carry certain weights (ballast) in the front section of the car, and these weights must stay in place during crash safety tests—unless they're already part of the front wing structure. This ensures the car meets safety standards when tested.
- Ballast positioned ahead of the front axle reference line (XA=0) must be physically present during front impact crash tests
- The rule doesn't apply to ballast that's already integrated into the front wing's structural profile
- This regulation ensures safety compliance by verifying that weight distribution is maintained during crash scenarios
Official FIA Text
Any Ballast mounted ahead of XA=0 not mounted within forward-most profile of Front Wing Profiles must be present during Front Impact Structure Dynamic Test defined in Article C13.6.3.
