Stilo ST6 FN ABP Composite Helmet FIA 8859-2024

The Stilo ST6 FN ABP Composite Helmet is the composite-shell entry point for open wheel and formula racing competitors who need FIA 8859-2024 ABP (Advanced Ballistics Protection) certification — the standard mandated or recommended for Formula Ford, Formula 4, and lower-level open wheel categories in NZ and AU. It delivers the same ABP forehead protection as the carbon version at a more accessible price point, thanks to its composite shell construction.

Important: FIA 8859-2024 ABP is not permitted in FIA Formula 1, Formula 2, Formula 3, Toyota Racing Series (TRS), or Formula Regional Oceania Championship (FROC). Those categories mandate FIA 8860-2018. This helmet is the correct and recommended choice for Formula Ford, Formula 4, club formula, and other lower-level open wheel categories. Always verify your specific event regulations.

Why ABP Matters for Open Wheel Racing

Advanced Ballistics Protection (ABP) adds a reinforced extended zone across the forehead area of the helmet shell. In open wheel and formula racing — where the driver's head is fully exposed and debris, stones, and tyre rubber are a constant hazard — ABP provides critical additional impact and penetration resistance beyond the standard FIA 8859-2024 certification. For lower-level open wheel categories, ABP is the recommended or mandatory specification.

Frequently Asked Questions

Is this helmet permitted in TRS, FROC, F1, F2, or F3?

No. TRS, FROC, Formula 1, Formula 2, and Formula 3 mandate FIA 8860-2018 certification. This helmet is certified to FIA 8859-2024 ABP, which is not accepted in those categories. For TRS and FROC, see the ST6 FN 8860 Carbon.

What is the difference between the composite and carbon ABP versions?

Both helmets carry the same FIA 8859-2024 ABP certification and Advanced Ballistics Protection. The composite shell is heavier than carbon but comes at a lower price point. If weight saving is a priority, see the ST6 FN Carbon ABP.
