The Legendary Stilo Carbon Helmet - Forever Ahead
For over 25 years, Stilo has led racing helmet innovation and the ST6 Carbon ushers in a bold new chapter. With input from top programs, engineers refined the front and top aerodynamics for stable performance at speed. Developed with drivers from Formula One and endurance racing, the ST6 reflects real-world needs at every level.
The ST6 Carbon is among the lightest full-face helmets available, pairing airflow, visibility, and comfort with modern safety. From the track-tested aero to the dual-lock visor system, every update is aimed at confidence and consistency behind the wheel.
The ST6 improves on the market-leading ST5 in key areas:
- 10% lighter than Stilo ST5
- 26% more airflow than Stilo ST5
- 11% more visibility
- Refined liner and cheek pads
- More shell sizes to optimize weight
- Reworked visor construction for durability and easy care
- Updated visor hardware for reliability

What’s Changing in SA2025 Auto Racing Helmets?
SA2025 helmets are here, and while the changes may not be groundbreaking, they represent an important evolution in motorsport safety. According to the Snell Memorial Foundation, the SA2025 standard is an evolutionary update from SA2020—not a complete overhaul. Unlike the M2025 motorcycle standard, which adds rotational impact testing, the SA2025 auto racing helmet standard does not include rotational force requirements.
Key SA2025 Helmet Safety Enhancements:
-
Increased Impact Protection: SA2025 helmets are required to handle slightly higher impact speeds and achieve lower maximum peak G-force thresholds across all head-form sizes.
-
Global FIA Alignment: These updated requirements bring the SA2025 standard into alignment with the new FIA 8859-2024 helmet safety regulation, creating more consistency across international motorsports.
In short: SA2025 helmets are designed to offer enhanced linear impact protection, making them the safest Snell-rated auto racing helmets to date. Whether you're a competitive racer or a weekend track day enthusiast, upgrading to an SA2025-certified helmet ensures compliance with future racing regulations and gives you peace of mind at speed.
Stilo ST6 FN Carbon Fiber SA2025 Helmet FAQs:
Is this helmet Snell SA2025 certified? Yes, this listing reflects SA2025 certification for U.S. auto racing.
What does FN mean? FN is the open-ear version for maximum cockpit awareness and airflow; GT includes earmuffs for noise reduction and comms.
Can I reuse my ST5 shields? No. The ST6 uses its own shield system; choose ST6-specific shields and hardware.
How should I choose my size? Measure head circumference and consult the size/pad chart. If between sizes, many drivers prefer the tighter fit for stability.
Measuring Your Head For Your New Stilo ST6 FN Carbon Fiber Helmet
The most effective helmet is one that fits properly. Have an assistant measure around your head about an inch above the eyebrows, around the largest point at the back, and back to the front. Take multiple measurements and use the largest.
