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. This helmet will ship with signature required for delivery.  

Stilo ST6 FN ZERO Carbon Fiber 8860-2018 Racing Helmet The Stilo ST6 FN ZERO Carbon Fiber Racing Helmet is the flagship non-ABP open-wheel helmet in the ST6 range. Developed using experience from Formula One and other elite racing categories, it combines Stilo’s ultra-light Puro Tech carbon construction with improved aerodynamics, increased airflow, greater downward visibility, and FIA 8860-2018 advanced helmet protection. 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.

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.

Bell HP77 EVO-IV 8860-2018 ABP Carbon Fiber Helmet   The Bell HP77 EVO-IV 8860-2018 ABP Carbon Fiber Helmet delivers Formula-level protection, aerodynamic performance, cooling, and optical clarity for professional open-wheel and open-cockpit racing. Developed from Bell’s multiple Formula One World Championship-winning HP7 platform, the HP77 EVO-IV combines an ultra-lightweight carbon fiber shell with a narrow eyeport and integrated ballistic materials designed to provide additional protection from flying debris. Homologated to the FIA 8860-2018 ABP advanced helmet standard, the HP77 EVO-IV is engineered for drivers competing where helmet weight, high-speed stability, visibility, ventilation, and impact-energy management must perform at the highest level. Updated shell construction, a multi-piece energy-absorbing liner, optical-grade DSAF visor, and carefully managed airflow make the HP77 EVO-IV Bell’s premier helmet for demanding formula and exposed-cockpit applications. Championship-Proven Bell HP7 Heritage The HP77 EVO-IV is based on the Bell HP7, a helmet platform proven through multiple Formula One World Championships. Bell used this foundation to create an ABP-specific helmet for drivers who need the highest level of frontal protection available within the FIA 8860-2018 helmet standard. Its compact carbon shell, aerodynamic profile, narrow eyeport, advanced ventilation, and integrated cockpit-system channels reflect the requirements of professional drivers competing at extreme speeds. Every major component is designed to work as part of a complete protective system without adding unnecessary exterior bulk or weight. FIA 8860-2018 ABP Advanced Helmet Protection The Bell HP77 EVO-IV is homologated to the FIA 8860-2018 ABP standard. ABP stands for Advanced Ballistic Protection and identifies helmets that incorporate additional protection around the frontal area above the visor. The HP77 EVO-IV uses a visor opening positioned approximately 12 mm lower than the original HP7-style opening. High-strength ballistic materials are integrated into the reinforced frontal structure to increase protection from medium-sized debris and objects that may strike the helmet in an open cockpit. The reduced eyeport is an intentional part of the certified ABP design. Adding an external visor panel or reinforcement strip to a conventional helmet does not convert that helmet into an FIA 8860-2018 ABP model. The complete helmet must be manufactured, tested, labeled, and homologated in its ABP configuration. High-Strength and High-Modulus Carbon Fiber Shell The HP77 EVO-IV shell is manufactured using high-strength and high-modulus carbon fibers selected to provide excellent structural performance at an exceptionally low weight. The shell is finished in exposed matte carbon, giving the helmet a purposeful appearance without disguising its advanced composite construction. Reducing helmet weight can help limit strain on the driver’s head and neck during repeated high-g braking, cornering, impacts, and long race sessions. The compact shell profile also supports improved cockpit clearance and allows the helmet to move more cleanly through high-speed airflow. Multi-Density, Multi-Piece Energy-Absorbing Liner Inside the carbon shell is an advanced multi-density, multi-piece liner engineered to manage different impact loads. Rather than relying on a single uniform layer, the liner uses multiple sections and material densities to help absorb and distribute impact energy across the helmet structure. This construction allows Bell to tune individual areas of the liner according to the protection required around the crown, sides, rear, chin bar, and frontal sections of the helmet. The result is a complete impact-management system designed around the demanding performance requirements of FIA 8860-2018 ABP. Narrow ABP Eyeport for Open-Cockpit Protection The HP77 EVO-IV has a noticeably narrower eyeport than a conventional full-face racing helmet. The reduced opening allows the reinforced upper frontal structure to extend farther downward, increasing the protected area above the visor. Although the eyeport is compact, its shape is developed to preserve the forward and peripheral visibility needed in formula and open-cockpit racing. Drivers should verify that the ABP eyeport provides suitable visibility for their seating position, mirrors, steering-wheel display, and cockpit layout before competing. Optical-Grade Double Screen Anti-Fog Visor The Bell HP77 EVO-IV includes an optical-grade, injection-molded Double Screen Anti-Fog visor. Commonly known as DSAF, this visor construction uses two viewing layers to create an insulating barrier that helps control condensation across the shield. The DSAF system is especially valuable in wet weather, cool temperatures, high humidity, driver changes, and other conditions where rapid temperature differences can cause a conventional visor to fog. Injection molding also supports consistent thickness and optical quality across the curved viewing area. The HP77 EVO-IV uses Bell SE077 3 mm replacement shields. Drivers should confirm that any clear, tinted, mirrored, or specialty visor is specifically listed for the HP77 EVO-IV and its installed pivot hardware. 12-Channel Top and Chin-Bar Ventilation Bell equips the HP77 EVO-IV with a powerful top and chin-bar ventilation system incorporating 12 intake and extraction channels. Fresh air enters through the upper and lower intake areas, moves through the helmet, and helps carry heat and moisture away from the driver. The installed intake system includes a two-part center intake and low-profile side components. The low-profile design helps maintain airflow while reducing unnecessary aerodynamic disturbance around the top of the helmet. Effective ventilation can improve driver concentration and comfort while also supporting the performance of the anti-fog visor system. Actual airflow will vary according to vehicle speed, windscreen design, cockpit turbulence, head position, and installed aerodynamic accessories. Aerodynamic Shell and Visor Integration The shell and visor were developed together to improve aerodynamic performance in exposed high-speed airflow. The smooth transition between the visor, shell, intakes, and rear profile helps manage turbulence around the helmet and reduce unwanted lifting or buffeting. Bell also designed the helmet to help reduce internal wind noise and improve the energy-management capability of the complete shell and visor system. Optional top spoilers, top gurneys, and chin-bar gurneys are available separately. These components allow the helmet’s aerodynamic balance to be adjusted for different cockpit designs, windscreens, seating positions, and airflow conditions. Integrated Communication and Hydration Channels Channels integrated into the HP77 EVO-IV facepiece provide multiple routing options for radio and hydration equipment. These passages help teams install compatible communication wiring or a drinking tube without placing excessive pressure between the helmet liner and the driver’s head. A frontal chin-bar opening for a drinking tube is available as an optional special-order configuration. Radio electronics, microphones, earbuds, wiring, connectors, drink tubes, valves, and hydration components are not included unless specifically selected with the helmet. Any installed communication or hydration equipment must be routed carefully so it does not interfere with helmet fit, visor operation, chin-strap security, visibility, or head-and-neck-restraint use. Factory-Installed HANS Anchors Factory-installed HANS anchors are included as original equipment. These attachment points allow a compatible head-and-neck restraint to be connected to the helmet using the restraint manufacturer’s approved tether system. The anchors should not be removed, altered, repositioned, or replaced with unapproved components. Always follow the helmet and restraint manufacturers’ instructions and confirm the applicable head-and-neck-restraint requirements with the sanctioning body. Synthetic Rubber Eyeport Seal A synthetic rubber gasket surrounds the visor opening to help reduce the entry of water, dust, rubber debris, and other contaminants. When the visor is properly closed, the gasket creates a more controlled seal between the shield and helmet shell. The eyeport gasket should be inspected regularly for cuts, deformation, looseness, or contamination. Damaged seals should be replaced with the correct Bell component rather than repaired with adhesive or non-approved material.

Confirm the exact HP77 EVO-IV configuration before purchasing replacement visor hardware or aerodynamic components. How to Measure for the Bell HP77 EVO-IV Use a soft measuring tape to measure around the widest circumference of the head. Position the tape approximately one inch above the eyebrows, pass it above the ears, and wrap it around the widest point at the rear of the head. Keep the tape level and comfortably snug without pulling it excessively tight. Take the measurement two or three times and use the largest consistent result when reviewing the Bell helmet sizing chart. The HP77 EVO-IV should create firm, even pressure around the crown, sides, rear, and cheeks. The helmet should not rotate independently when the chin strap is secured. A new helmet may feel tighter than expected because the interior padding will settle slightly with use, but it should not create sharp or painful pressure points. Because the HP77 EVO-IV uses a narrow ABP eyeport, drivers should also confirm that their eyes align correctly within the opening and that the helmet provides adequate forward and peripheral visibility in their normal driving position.

For drivers who demand the utmost from their car Designed and tested specifically for track day enthusiasts and for drivers who demand the utmost performance from their cars, these kits offer superlative performance for both normal driving and demanding track day sessions. Brembo kits consist of cross-drilled or slotted ventilated, one-piece or composite discs and aluminium calipers with 4, 6 or 8 pistons; a complete set of high performance pads; metal-braided hoses and high quality hardware.     ​Solutions and technologies born on the race trackBraking systems consisting of motorsports-derived components offering levels of technology and performance without par on the market today and embodying the purest expression of Brembo's state-of-the-art technology.The kit consists of aluminium calipers with opposed pistons which, depending on the car model and in increasing order of performance, may be composite, monoblock or even billet monoblock components, combined with cross-drilled or slotted one-piece or composite oversized discs.Brembo kits combine the best solutions available to offer the perfect solution for the individual characteristics of each model.The heart of the kit consists of aluminium calipers. These are also available as monoblock parts machined from a single billet of cast aluminium, which ensure outstanding rigidity and minimised deformation. The discs supplied in the kit, which may either be floating or one-piece, depending on the specific car model, feature an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%.Cross-drilled and slotted finishes are designed and executed with meticulous precision. These holes or slots in the braking surface help dissipate heat and eliminate brake dust and gases. A set of high-performance brake pads with specific friction materials for each application, TÜV/DOT homologated metal-braided hoses, an adapter and high-quality fastener hardware complete the kit.      More braking torque and thermal capacity on the trackUsing radial-mounted fixed calipers together with oversized discs gives the system greater braking torque and superior thermal capacity. The result is a braking action that is noticeably more immediate and decisive even in normal road usage, and is extraordinarily powerful and consistent under the repeated loads of track use. Fixed calipers improve the durability and efficiency of the system: the opposed multiple pistons act on the pads with more precision, due to the smaller piston diameter and the reduced pressure exerted on each individual piston, while the greater overall surface area between the pads and pistons results in more uniform friction surface wear. The superlative stiffness of the calipers and the metal braided hoses reduce brake fluid absorption. The result is improved, more stable brake pedal pressure, making it possible to modulate braking force more precisely and enhancing pedal feel. Featuring a hat in aluminium alloy, the oversized floating disc system reduces unsprung mass (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float. This characteristic, together with the greater dimensions of the braking rotor surface, improves the dispersion of the heat generated by the repeated, intense thermal stress that the discs are subjected to, for consistent braking performance and pedal feel even after numerous laps on the track.     Eye-catching, unique looksWith a combination of painted calipers (available in red, black or silver) flaunting the Brembo logo, and slotted or cross-drilled discs, the Gran Turismo kit gives an unmistakably sporty, eye-catching look to the car, offering that extra special touch for drivers who want their vehicle to stand out from the crowd.Catering for the more discerning driver is the GT-R line of kits. These offer even more performance and consist of billet-monoblock calipers, slotted discs in diameters up to 405 mm and special high performance pads.
