Stilo ST6 FN Composite SA2020 Racing Helmet
The Legendary Stilo FN Composite Helmet - Forever Ahead
For over 25 years, Stilo has lead the way in racing helmet innovation and the new ST6 line marks a bold new chapter. With input from Porsche and F1 teams, Stilo developed enhanced front- and top aerodynamics to deliver exceptional performance from the new Stilo ST6 line of helmets. Developed with the world's top drivers from Formula One and endurance racing, the ST6 reflects real-world needs at every level of auto racing.
The Stilo ST6 composite helmet is one of the lightest composite helmets on the market. It features enhanced airflow, visibility, and comfort while maintaining market-leading safety standards. Developed with input from the Aston Martin F1 team, every feature of the ST6 -- from the track-tested aerodynamics to the cutting edge dual-lock visor system -- is designed to give racers a performance edge.
The brand new Stilo ST6 helmet improves on the market-leading Stilo ST5 in every way, including the following:
10% lighter than Stilo ST5
26% more airflow than Stilo ST5
11% more visibility
More comfortable liner and cheek pads
More shell sizes for lower weight
Improved visor construction for durability and ease of care
Higher-quality visor hardware increases reliability
Stilo ST6 FN Composite Auto Racing Helmet Features
Puro Tech: Stilo's proprietary carbon fiber manufacturing process eliminates the need for extra lacquers and additional coatings, minimizing the weight of your new helmet. With the Puro process, Stilo delivers the lightest and safest helmet on the market.
Added Shell Size: now offered in four shell sizes, the Stilo ST6 FN auto racing helmet gives you the lightest and smallest shell size possible for your head shape.
Increased Airflow Design: by utilizing key partnerships with Formula One teams, Stilo has redesigned the ST6 front ventilation to increase airflow while maximizing safety. The new Stilo ST6 also comes standard with ventilation holes in the top, channeling airflow through the EPS foam to reduce sweat and moisture, keeping you performing at your best.
Increased Downward Visibility: with input from professional drivers around the globe, Stilo has increased the downward field-of-view of the Stilo ST6, making harness fastening easier during driver changes and giving you greater situational awareness on the track.
Interior Comfort: new and improved cheek padding in the Stilo ST6 was designed to enhance aero stability and increase comfort.
Injection Molded Visor: the brand new visors for the ST6 provide exceptionally clear visibility and are coated in a new high-performance, washable anti-fog treatment.
Dual Visor Lock: pioneering the industry, the dual visor lock on the Stilo ST6 complies with FIA standards in both the fully closed and ventilation positions.
Updated Visor Hardware: engineered for easier visor installation and smoother actuation, this visor hardware can be purchased in a variety of anodized finishes.
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.

Measuring Your Head For Your New Stilo ST6 FN Composite Helmet
The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.

Thunderhill is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline.This Girodisc system upgrades the OEM brakes to a two-piece steel disc and aluminum hat. This two-piece "floating rotor" design will bolt directly to the Viper front or rear and work flawlessly with OEM calipers.Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response.Combined with Pagid or PFC performance brake pads and Thunderhill RF-1 brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving.The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc.The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors.This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs.Sold/priced per pair.

When used with Pagid racing brake pads and Thunderhill RF-1 racing brake fluid, you have the best possible solution to overheating, cracking, and warping rotors.
The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA and is made to the same specification with the same material used by professional racing organizations. The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.
The rotor and hat mount together through a floating mount system which utilizes ten high-strength alloy steel drive pins manufactured by Girodisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by grade12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.
The two-piece Girodisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling.

The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Sold/priced per pair.
