Stilo ST5 FN 8860-2018 ABP Carbon Fiber Racing Helmet

FIA 8860 Certification valid thru 2033 for these ST5 FN 8860 ABP Helmet

The Stilo ST5 FN 8860-2018 ABP Carbon Fiber Racing Helmet is engineered for professional drivers who demand one of the highest levels of helmet protection available in motorsports. Designed around the stringent FIA 8860-2018 ABP standard, the ST5 FN ABP combines an extremely lightweight carbon-fiber shell with Advanced Ballistic Protection developed for top-level open-wheel, prototype, endurance, and professional racing.

The FN designation stands for Stilo's Formula Naked configuration. Unlike the ST5 GT, the FN eliminates the external integrated side ports to reduce weight and create an exceptionally clean aerodynamic profile. The helmet can still be configured for communications, forced air, hydration, and helmet eject systems through Stilo's purpose-built accessory system.

For drivers competing at the highest levels of motorsport—or racers who simply refuse to compromise on protection—the ST5 FN 8860-2018 ABP delivers exceptional safety, low weight, comfort, and professional-grade functionality.

FIA 8860-2018 ABP Advanced Ballistic Protection

ABP stands for Advanced Ballistic Protection. FIA developed the ABP specification to provide increased protection to the frontal area of the helmet, particularly around the forehead and visor opening.

The ABP design incorporates additional protection directly into the helmet structure instead of relying on the separate Zylon visor panel used with previous-generation FIA 8860-2010 Formula 1 helmets.

The FIA 8860-2018 ABP testing procedure includes demanding impact and projectile testing intended for motorsports where drivers may be exposed to debris and other high-energy impacts. The result is an exceptionally protective helmet designed for the highest levels of professional competition.

Lightweight Carbon Fiber Construction

The Stilo ST5 FN 8860-2018 ABP is constructed from 100% medium-tensile carbon fiber, providing an outstanding combination of strength, rigidity, impact performance, and low weight.

Reducing helmet weight is especially important in open-wheel and high-downforce race cars, where sustained lateral G-forces can place significant loads on the driver's head and neck. The lightweight construction of the ST5 FN helps reduce fatigue during long sessions without sacrificing the protection required by the FIA 8860-2018 ABP standard.

Designed for Open-Cockpit and Professional Racing

The ST5 FN ABP is particularly well suited for open-wheel and open-cockpit racing where the driver's helmet is more exposed to airflow, debris, and other environmental factors.

The ABP configuration uses a reduced-height eyeport and specialized visor to increase protection around the forehead area. Combined with the aerodynamic ST5 shell, the helmet provides a compact and streamlined profile for high-speed racing.

Formula Naked FN Design

The FN or Formula Naked configuration removes the external side accessory ports found on the Stilo ST5 GT. Eliminating these ports reduces weight and creates a smooth exterior shell ideally suited to Formula, prototype, and open-wheel applications.

Despite the clean exterior, the ST5 FN remains compatible with a wide range of Stilo accessories and can be configured for driver communications, hydration, top forced air, and helmet eject systems.

Integrated Accessory Capability

The ST5 FN was designed so important racing accessories can be added without creating unnecessary cables, hoses, or components hanging around the driver's helmet.

• Compatible with Stilo FN communication systems
• Compatible with Stilo top forced-air systems
• Compatible with helmet eject systems
• Compatible with hydration systems
• Available aero accessories for open-cockpit applications
• Compatible with Stilo ABP-specific visors

Communications, forced-air components, hydration equipment, and other optional accessories are sold separately unless specifically included with the selected configuration.

Factory-Installed HANS Posts

The Stilo ST5 FN 8860-2018 ABP comes with factory-installed HANS posts, making it ready for use with compatible head-and-neck restraint systems.

Factory installation provides a clean, properly positioned attachment solution without requiring the racer to install restraint anchors separately.

ST5 ABP Visor System

The ABP helmet uses a specialized reduced-height eyeport and visor designed specifically around the Advanced Ballistic Protection requirements.

Stilo's center visor locking system allows the shield to be opened and closed easily, even while wearing racing gloves. Tear-off posts allow the helmet to be configured for racing environments where debris and contamination can quickly affect visibility.

Important: Because of the different eyeport design, always verify that replacement shields and accessories are specifically compatible with the ST5 ABP helmet.

Improved Interior Comfort

Stilo redesigned the ST5 interior with more contoured cheek pads and padding designed to improve comfort and helmet stability.

Removable earmuff cushions help isolate the driver's ears from surrounding noise, creating a quieter environment and providing dedicated space for compatible communications equipment.

Eight-Point Top Ventilation

Eight ventilation openings across the top of the helmet help manage airflow and can also be used with the optional Stilo ST5 Top Air System.

A forced-air system can be especially valuable in endurance racing, enclosed cockpits, and hot-weather competition where maintaining driver comfort and concentration becomes increasingly important.

Stilo ST5 FN 8860-2018 ABP Helmet Sizing Chart

Stilo ST5 full-face helmets use two different shell sizes to provide a better-fitting helmet without adding unnecessary padding and weight.

Discovery Parts Fit Note: We have found that customers who normally wear a size 59 in some other helmet brands are often more comfortable moving to a Stilo size 60. Stilo helmets tend to fit slightly snugger than many competing brands, so accurate measurement is important.

How to Measure for a Stilo Helmet

Use a flexible cloth measuring tape and measure around the widest part of your head. Position the tape approximately one inch above your eyebrows, run it above your ears, and continue around the widest portion at the back of your head.

Take the measurement two or three times and use the largest number. A properly fitted racing helmet should fit firmly and evenly around your head without creating painful pressure points.
