Stilo ST6 FN ZERO Carbon Fiber 8860-2018 Racing Helmet

Designed for drivers who require maximum protection without the reduced eyeport of an ABP helmet, the ST6 FN ZERO delivers a wide field of vision, a compact four-shell sizing platform, redesigned interior padding, and an injection-molded visor secured by Stilo’s dual-position visor locking system.

Flagship ST6 Helmet for Formula and Open-Wheel Racing

The ST6 FN configuration was developed specifically for open-wheel and open-cockpit competition. Its streamlined shell, stable interior, improved airflow, and expanded downward field of view address the conditions drivers experience in formula cars, prototypes, and other exposed-cockpit vehicles.

The FN interior does not rely on permanently integrated GT-style radio electronics. Instead, specially designed padding channels make it easier to route optional communication equipment, air hoses, and hydration components according to the requirements of the driver and vehicle.

FIA 8860-2018 Advanced Helmet Protection

The Stilo ST6 FN ZERO is homologated to the FIA 8860-2018 advanced helmet standard under homologation number AH.030.24-C. This professional-level standard requires significantly higher impact, penetration, shell-strength, and flame-resistance performance than entry-level motorsport helmet certifications.

This model is the standard non-ABP version. It does not include the extended forehead protection and reduced eyeport found on the ST6 FN ZERO ABP. Drivers should confirm whether their championship requires standard FIA 8860-2018 or FIA 8860-2018-ABP homologation before ordering.

Puro Tech Carbon Fiber Construction

The ST6 FN ZERO uses Stilo’s proprietary Puro Tech carbon fiber manufacturing process. Puro Tech reduces the need for heavy cosmetic lacquer and additional external coatings, allowing the natural carbon shell to remain visible while minimizing unnecessary weight.

Each shell is produced with careful control of its carbon layers to create a lightweight, compact helmet capable of meeting the demanding performance requirements of FIA 8860-2018. The exposed carbon finish also gives every helmet the distinctive appearance associated with Stilo’s premium ZERO range.

Four Shell Sizes Reduce Weight and Exterior Bulk

The ZERO range uses four exterior shell sizes so each interior size can be placed into the smallest appropriate helmet shell. This creates a more proportional fit and avoids surrounding smaller head sizes with unnecessary material and exterior volume.

A smaller, lighter shell can improve cockpit clearance, aerodynamic stability, balance, and comfort. It can also reduce the strain placed on the driver’s head and neck during long sessions or repeated high-g cornering.

Major Improvements Over the Stilo ST5 ZERO

The ST6 platform advances the successful ST5 design with improvements focused on weight, airflow, visibility, comfort, and visor operation. Key updates include:

• Approximately 10% lower weight than the comparable ST5
• Approximately 26% more airflow
• Approximately 11% greater visibility
• Improved front and upper-shell aerodynamics
• Redesigned cheek pads for better comfort and stability
• Additional shell sizing for a smaller, lighter fit
• Injection-molded visor construction
• Washable high-performance anti-fog visor treatment
• Updated visor pivots and mounting hardware
• Smoother visor movement and easier shield replacement
• Improved routing channels for electronics, air, and water systems

Formula One-Derived Airflow and Aerodynamics

Stilo redesigned the ST6 ventilation system using experience gained from Formula One and other professional racing programs. Revised front vents direct fresh air into the helmet while maintaining the structural integrity required by the FIA standard.

Ventilation openings in the top of the shell channel air through the EPS liner to help move heat and moisture away from the driver’s head. This increased airflow can reduce discomfort, visor fogging, and concentration loss during hot or physically demanding races.

The front profile and upper shell were also shaped to provide greater aerodynamic stability in high-speed airflow. This is particularly important in open-wheel cars, where the helmet is directly exposed to turbulence around the cockpit and roll structure.

Increased Downward Field of View

The ST6 eyeport provides greater downward visibility than the ST5. This allows drivers to see steering-wheel displays, switches, harness hardware, cockpit controls, and dashboard information with less head movement.

The wider usable viewing area also supports better peripheral awareness when approaching other cars, locating corner apexes, or checking mirrors and display screens inside a tightly packaged cockpit.

Redesigned Cheek Padding and Interior Stability

Stilo redesigned the ST6 cheek pads to provide a more secure and comfortable fit. The updated shape helps stabilize the helmet during braking, cornering, vibration, and high-speed airflow without relying on excessive pressure against the driver’s face.

The improved interior also includes accessible channels for routing optional communication wiring, air-system components, and hydration equipment. This allows the helmet to be customized without forcing equipment between the liner and the driver’s head.

Injection-Molded Visor with Washable Anti-Fog Treatment

The ST6 FN ZERO uses a high-performance injection-molded visor designed to provide consistent optical clarity across its curved viewing area. This production method improves dimensional consistency and helps reduce the distortion that can occur through conventional formed racing shields.

The visor receives Stilo’s washable anti-fog treatment to help maintain clear vision during changing temperatures, humid weather, wet races, and extended driving sessions. The visor should be cleaned only with soft materials and suitable water-based products.

Compatible ST6 replacement visors are available in clear, smoked, mirrored, double-glazed, and other specialized configurations. Drivers should select only non-ABP ST6 visors for this helmet.

Dual-Position Central Visor Lock

Stilo’s central visor locking system provides two positively secured operating positions.

• Fully Closed: Secures the visor firmly against the eyeport seal for maximum protection and aerodynamic stability.
• Ventilation Position: Holds the visor slightly open while keeping it mechanically locked and controlled.

The ventilation position allows additional airflow without leaving the visor unsecured. The central mechanism also closes the visor evenly and remains accessible while the driver is wearing racing gloves.

Updated Visor Hardware

The ST6 introduces redesigned pivot hardware and visor sliders for smoother movement, easier installation, and improved reliability. Replacement hardware is available in multiple anodized finishes for drivers who want to personalize the helmet’s appearance.

ST5 visors and ST5 visor hardware are not interchangeable with the ST6 system. Replacement shields and components must be specifically listed for the Stilo ST6.

Ready for Optional Communications, Air, and Hydration

The ST6 FN uses a non-integrated equipment layout. Padding channels make it easier to install compatible earbud systems, microphones, radio wiring, air components, and hydration equipment without permanently building those items into the helmet.

Communication electronics, speakers, earbuds, microphones, radio adapters, air-system hardware, and drinking-system components are optional unless specifically included with the selected configuration.

Available electronic configurations vary between IMSA, NASCAR, Stilo, Peltor, MRTC, Raceceiver, and other communication systems. Connector compatibility should be confirmed before ordering an electronic kit.

ST6 FN ZERO Versus the ST6 FN ZERO ABP

The standard ST6 FN ZERO has a conventional full-face eyeport and carries FIA 8860-2018 homologation without the ABP designation. It provides a wider opening for drivers whose series does not require Advanced Ballistic Protection.

The ST6 FN ZERO ABP adds an extended protective structure above the visor and uses a reduced eyeport to satisfy FIA 8860-2018-ABP requirements. An ABP visor, reinforcement strip, or other accessory cannot convert the standard ST6 FN ZERO into an ABP-homologated helmet.

ST6 FN ZERO Versus the ST6 GT ZERO

The ST6 FN ZERO is configured for open-wheel and open-cockpit racing, with a streamlined non-integrated interior and routing provisions for optional equipment.

The ST6 GT ZERO is intended primarily for enclosed race cars and places greater emphasis on cockpit communication, noise control, adjustable ear padding, and GT-style hydration integration. Both use premium ZERO carbon construction, but their interiors and intended installations are different.

How to Measure for a Stilo ST6 Helmet

Use a soft measuring tape to measure around the widest circumference of your head. Position the tape approximately one inch above the eyebrows, pass it above the ears, and wrap it around the widest point at the back of the head.

Keep the tape level and comfortably snug without pulling it tight. Take the measurement two or three times and use the largest consistent result when reviewing the Stilo sizing chart.

A properly fitted racing helmet should create firm, even contact around the crown, sides, and cheeks. It should not rotate independently when the chin strap is secured, but it should not create sharp or painful pressure points.
