Stilo Venti WRC ZERO 8860-2018 Carbon Fiber Helmet Uncompromising Safety and Performance Stilo Venti WRC ZERO 8860-2018 Carbon Fiber Helmet The Stilo Venti WRC ZERO 8860-2018 Carbon Fiber Helmet is engineered for professional rally drivers and co-drivers who demand elite protection, exceptionally low weight, and clear in-car communication. Combining an advanced carbon fiber shell with Stilo’s weight-saving PURO technology, integrated WRC electronics, and FIA 8860-2018 certification, this open-face rally helmet is built for the most demanding stages in motorsport. The Venti WRC ZERO is the premium, weight-focused version of Stilo’s championship-winning Venti rally helmet. Its compact shell, noise-attenuating earmuffs, adjustable microphone, and recessed communication connection create a complete helmet and intercom platform designed around the needs of a rally crew. FIA 8860-2018 Protection for Elite Competition The Stilo Venti WRC ZERO is certified to the FIA 8860-2018 advanced helmet standard. Developed for high-level motorsport, this certification subjects the helmet to demanding impact, penetration, flame-resistance, and structural performance requirements. Its high-tensile carbon fiber shell delivers exceptional strength without the unnecessary bulk associated with heavier helmet constructions. Factory-fitted HANS post anchors allow the helmet to be connected to a compatible frontal head restraint without requiring separate anchor installation. Ultra-Light ZERO Carbon Construction Every part of the Venti WRC ZERO is designed with weight reduction in mind. Stilo’s PURO carbon technology eliminates the need for a conventional final clear-coat layer, reducing unnecessary material while revealing the helmet’s distinctive raw carbon fiber finish. The result is the lightest helmet configuration in the Venti WRC range, with a listed weight of approximately 2.6 pounds, depending on helmet size and equipment configuration. Reducing weight at the driver’s head can help limit neck fatigue during long rally stages, endurance events, and repeated high-load driving conditions. Stilo uses three shell sizes across the Venti WRC range so each helmet can maintain a more compact and proportional exterior profile. This approach helps prevent smaller sizes from being placed inside an unnecessarily large or heavy shell. Integrated Stilo WRC Communication System The Venti WRC ZERO is designed around Stilo’s integrated WRC intercom system. Noise-attenuating earmuffs surround the built-in speakers, helping isolate the driver or co-driver from engine, drivetrain, gravel, and cabin noise. An adjustable magnetic dynamic noise-canceling microphone is mounted on a reshaped boom designed to improve voice clarity. The microphone position can be adjusted closer to or farther from the mouth to achieve clearer communication while reducing unwanted ambient sound. This integrated design eliminates the need to install a separate headset inside the helmet, creating a cleaner fit and reducing interference between the communication equipment, helmet padding, and the wearer’s ears. Wireless and Hard-Wired Intercom Compatibility The helmet’s recessed side communication port is shaped to accept the Stilo WL wireless key, sold separately. Once installed, the wireless key follows the contour of the shell to help prevent interference with FHR straps and helmet hardware. The integrated electronics are also compatible with traditional hard-wired Stilo DG and WRC-series amplifiers. This allows a competitor to use the same helmet in vehicles equipped with either Stilo wireless or conventional wired communication systems. Driver-Focused Visibility and Ventilation The redesigned shell and adjustable peak provide the visibility needed for constantly changing rally conditions. The peak can be raised or lowered to help manage low-angle sunlight, glare, and changing terrain without obstructing the driver’s forward view. The Venti WRC ZERO is also compatible with Stilo short visors, sold separately, for competitors who want additional eye protection. Integrated top ventilation openings help reduce heat and moisture buildup and allow the helmet to be used with a compatible Stilo Top Air system. Comfort for Long Rally Stages Updated interior padding works with the helmet’s soft noise-attenuating earmuffs to create a secure and comfortable fit. Expanded-polystyrene cheek protection supports the sides of the face while preserving the acoustic isolation required for clear communication. The combination of reduced shell weight, improved padding, sound insulation, and integrated electronics makes the Venti WRC ZERO especially well suited to drivers and co-drivers who remain helmeted for extended periods.

For competitors who prioritize every gram of equipment weight without sacrificing communication quality or FIA 8860 protection, the Stilo Venti WRC ZERO is the flagship choice within the Venti WRC range. How to Measure for a Stilo Helmet Use a soft measuring tape to measure around the largest circumference of your head. Position the tape approximately one inch above your eyebrows, pass it above your ears, and wrap it around the widest point at the back of your head. Take the measurement two or three times and use the largest result. Compare the measurement in centimeters with the Stilo sizing chart. The helmet should feel evenly snug around the entire head without creating sharp or painful pressure points. With the chin strap secured, the helmet should not rotate independently when moved from side to side. New helmet padding may relax slightly as it conforms to the wearer, so a new helmet should not begin with a loose fit.

Schuberth SF4 8860-2018 Carbon Fiber Helmet (Non-ABP) The Schuberth SF4 8860-2018 Carbon Fiber Helmet brings Formula-level materials, protection, and visor technology to professional GT, prototype, endurance, and open-cockpit drivers who do not require an ABP-homologated helmet. Handcrafted at Schuberth’s motorsport production facility in Italy, the SF4 combines an autoclave-cured carbon fiber shell with advanced ventilation, a Formula-derived injected visor, a two-stage visor lock, and extensive accessory compatibility. Its compact construction and refined interior are designed to support drivers through long race stints without compromising the advanced protection required by the FIA 8860-2018 standard. FIA 8860-2018 Advanced Helmet Protection The Schuberth SF4 is homologated to the FIA 8860-2018 advanced helmet standard under FIA homologation number AH.020.21-C. This is a professional-level motorsport helmet standard developed for demanding international competition. This specific SF4 is the non-ABP version. It does not incorporate the reduced eyeport and extended upper visor-area protection found on the SF4 ABP. That distinction makes the standard SF4 particularly well suited to GT cars, prototypes, endurance vehicles, and open-cockpit applications in which the governing series does not require Advanced Ballistic Protection homologation. Drivers should always verify the required helmet certification with their sanctioning body, race series, or event organizer before purchasing. Handcrafted Autoclave-Cured Carbon Fiber Shell Each Schuberth SF4 begins with a lightweight, hand-laid carbon fiber shell that is cured inside an autoclave. This specialized manufacturing process uses controlled heat and pressure to consolidate the carbon layers and create a strong, consistent helmet structure. The shell is handcrafted at Schuberth’s dedicated motorsport facility in Italy using production techniques developed through more than two decades of Formula racing experience. The result is a compact carbon helmet that balances structural strength, low weight, aerodynamic efficiency, and Schuberth’s unmistakable motorsport profile. Built for Long GT and Prototype Racing Stints The SF4 was developed for drivers who may remain helmeted for extended periods during endurance, GT, and prototype competition. Its compact shell profile, balanced construction, comfortable interior, and controlled airflow help reduce distractions during long sessions. The interior is shaped to maintain stable contact around the driver’s head and face without relying on excessive pressure. Multiple shell and interior configurations help Schuberth provide a more proportional fit across the helmet’s available size range. Because head shape and padding preference can affect fit, drivers should use the Schuberth sizing chart as a starting point and try the helmet on whenever possible. Formula-Derived Ventilation System Air channels integrated into the helmet’s EPS liner distribute fresh air through the interior while directing warm air away from the driver’s head. Schuberth states that, in unrestricted airflow, the system can provide up to 14 liters of fresh air per second at 100 km/h. The SF4 can be configured with optional ventilation accessories to suit different cockpit designs and airflow conditions. Available configurations may include individual ventilation scoops, top-air systems, chin ventilation components, and aerodynamic accessories. This flexibility allows the helmet to be adapted for enclosed GT cockpits, forced-air systems, prototypes, and open-cockpit vehicles. Injected Visor with Optical Clarity The Schuberth SF4 uses an injected visor developed from the brand’s Formula racing program. The manufacturing process is designed to minimize the optical distortion that can occur through the curved viewing area of a conventional racing shield. Schuberth offers multiple compatible visor options ranging from clear and dark tint to mirrored and multi-layer mirrored finishes. This allows drivers to select a visor suited to daytime, nighttime, bright-sun, or changing-weather competition. Standard SF4 visors are supplied with tear-off posts, allowing compatible tear-offs to be installed for events where dirt, rubber, oil, or debris may collect on the visor surface. Pinlock 120 Anti-Fog Performance Standard Schuberth SF4 visors are equipped with a Pinlock 120 anti-fog lens. The insert creates an insulating air pocket between the visor and the lens, helping reduce condensation when cockpit temperature, humidity, or weather conditions change. This system is especially valuable during endurance racing, wet events, cool-weather competition, and driver changes where moisture can quickly affect visibility. The Pinlock lens and visor should be cleaned only with appropriate materials and techniques to avoid damaging their optical or anti-fog surfaces. Central Two-Stage Visor Lock The SF4’s central visor mechanism is designed to close the visor evenly on both sides of the helmet. This symmetrical closure helps create consistent engagement with the eyeport seal and provides dependable visor operation while the driver is wearing racing gloves. The lock provides two functional positions: Stage One: Keeps the visor securely locked while allowing a small amount of ventilation into the helmet. Stage Two: Pulls the visor into a firmer seal to help block fine dust and water. The ventilation position allows the driver to increase airflow without leaving the visor unsecured. The fully sealed position is intended for conditions where dust, spray, or moisture protection takes priority. Communication-System Ready The Schuberth SF4 can be configured with optional integrated communication electronics. This allows the driver to build a professional radio setup suited to the team’s amplifier, connector, microphone, and audio requirements. Communication equipment is not included with the standard helmet unless it is specifically selected as part of the purchased configuration. Microphones, speakers, earphones, connectors, wiring, and related electronics may be sold separately. Any communication or earcup configuration must comply with the rules of the driver’s sanctioning body and race series. Customizable Aerodynamics and Airflow Different cars create different airflow patterns around the driver’s helmet. The SF4 platform can be adapted with compatible accessories to improve airflow, aerodynamic stability, cooling, and cockpit integration. Depending on the selected configuration, compatible Schuberth SF4 accessories may include: Top-air ventilation components Individual helmet ventilation scoops Chin ventilation scoops Rear and top aerodynamic spoilers Replacement clear, tinted, and mirrored visors Pinlock 120 anti-fog components Visor tear-offs Optional integrated communication electronics Replacement interior padding and fit components Accessory availability and compatibility can vary by helmet size, production version, and intended application. Non-ABP SF4 Versus the SF4 ABP The standard SF4 and SF4 ABP share Schuberth’s Formula-derived carbon construction and professional motorsport engineering, but they carry different FIA homologations. The non-ABP SF4 has a larger conventional eyeport and is intended for applications where FIA 8860-2018 certification is required but ABP homologation is not mandatory. The SF4 ABP uses an extended upper visor-area structure and reduced eyeport designed to satisfy Advanced Ballistic Protection requirements. An accessory visor strip or reinforcement panel does not convert the standard SF4 into an ABP-homologated helmet. The helmet remains certified only to the homologation stated on its FIA label.
