The Arai GP-7 SA2020 Auto Racing Helmet A driver favorite, the Arai GP-7 SA2020 helmet combines the most popular Arai features with new, improved upgrades. The Arai GP-7 is constructed with Arai’s own PBcLc (Peripherally Belted Complex Laminate Construction) helmet shell with the same shell shape as the top-of-the-range GP-7SRC model used in Formula 1. New ventilation, a soft EPS liner, and a wider eye port for optimized peripheral vision are part of this new shell which gives the driver notable strength and flexibility. Replaceable cheek pads make racing comfortable for any driver, as do the three larger, closeable intake vents and two larger exhaust vents on the ventilation system. The Arai GP-7 helmet is Snell SA2020 certified with factory-installed M6 washers/nuts. Drivers of any skill level can install their own Head and Neck Restraint system using a 6mm bolt. The FIA-8859-2015 certification sticker is applied to the interior liner of the helmet. Arai Positive Shield Latch Simple yet effective, the positive latch mechanism on the Arai GP-7 SA2020 helmet gives the driver solid shield latching, but is seamlessly integrated into the standard shield system for ease of use. New Shield Pivot for the Arai GP-7 The Arai GP-7 SA2020 features new shield pivot hardware with improved aerodynamics based on the updated track slider design. An increased peripheral field of view is featured on the 6 series, which surpasses the 5 series in visibility. The wider eye port, shield, and pivot hardware were all developed on the RC and adapted to the Arai GP-7 SA2020 helmet. Additional Arai GP-7 visor shields available here. ARAI GP-7 Increased Ventilation and Comfort Increased airflow is key to the GP-7 SA2020 helmet’s design. This includes bigger, closeable intake vents with large 10mm holes in both front and rear. Larger rear vents also provide better airflow. M6 HANS Anchors for the Arai GP-7 Helmet Drivers of all skill levels will appreciate the integrated, pre-installed M6 threaded washer/nut with 6mm threads which accepts a range of Head and Neck Restraint devices. A flat surface area around the mounting nut will let the anchor post base to rest flush along the surface of the helmet and around the full perimeter of the anchor base. FIA-8859-2015 certification sticker applied to the interior liner material. Featuring a Redesigned Chin Bar The Arai GP-7 SA2020’s new, ergonomic chin bar and ridge at the bottom edge of the shell lowers the center of gravity and increases the structural integrity of the helmet. Additional improvements include a rise in the shell above the shoulders for increased clearance. E-Ject Ready Crown Pad for Safer Removal Arai's optional E-Ject system can be easily accommodated via a pre-cut pocket under the helmet’s crown pad. This system makes removal of the helmet by track safety crew easier and less likely to jostle an unconscious driver's head in the event of an accident Arai GP-7 Auto Racing Helmet Details: Manufacturer: Arai Helmet Manufacturer part no.: GP7SA20 Snell SA2020 certified PBcLc (Peripherally Belted Complex Laminate) shell construction Removable chin liner to accommodate a drink system Sizes: 54cm (X-Small) to 60cm (Large) Exterior colors: Gloss White or Black Frost A Note About Helmet Fitment and Head Measurement 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. This helmet will ship with signature required for delivery.

Bell Kart Racing Helmets – Frequently Asked Questions (FAQ) Safety is critical in kart racing, and selecting the right helmet plays a key role in protecting your performance and well-being. If you're investing in your racing future, here's everything you need to know about Bell Kart Racing Helmets. General Helmet Questions What is the best helmet for kart racing?The Bell KC7-CMR is widely considered one of the best karting helmets, offering a carbon shell, Snell K2020 certification, and premium features for serious kart racers. Why do I need a racing helmet?Auto and kart racing helmets protect your head in high-speed accidents and shield against debris and, in some motorsports, fire. A helmet is the most important safety item you own. How do I choose the right size kart racing helmet?Use a flexible tape to measure your head just above the eyebrows and ears. Compare the result to Bell’s sizing chart. For step-by-step help, read our helmet fitting guide at Thunder Hill . What safety standards should I look for in a kart racing helmet?Snell K2020 certification is the top safety standard for kart racing. It ensures rigorous impact protection. Avoid DOT-only helmets—they are not rated for motorsport use. Can I use a motorcycle helmet for kart racing?No. Motorcycle helmets lack kart-specific certifications and may not offer the impact resistance and ventilation optimized for karting. Always choose a motorsport-rated helmet. How often should I replace my kart racing helmet?Replace your helmet every 3–5 years depending on use. Replace it immediately if it has been dropped, damaged, or involved in an impact—even if no damage is visible. Are expensive helmets safer than budget ones?Yes, in most cases. Premium helmets typically use lighter, stronger materials and offer better ventilation and comfort—all factors that reduce driver fatigue and improve safety. Helmet Use, Fit & Maintenance How do I maintain and clean my helmet?Use helmet-safe cleaners like the Molecule Care Kit. Do not submerge the helmet. Clean visors gently with microfiber cloths to avoid scratching. Do I need to wear a balaclava under my helmet?A balaclava improves comfort, protects the liner, and wicks away sweat. Fire-rated balaclavas are recommended and often required in competitive environments. Is the Snell K2020 rating important?Yes. It’s the most widely accepted kart helmet certification in national and international competition. Always check your series' rulebook for specific helmet requirements. Can I wear glasses with my kart helmet?Yes. Bell helmets feature wide eye ports compatible with most prescription glasses and racing eyewear, allowing for a stable, fog-free fit. Are carbon fiber helmets better?Carbon fiber helmets are lighter and stronger than traditional composite helmets. They reduce fatigue in long sessions while offering superior impact protection. Can I use a used helmet for racing?No. Damage or aging may not be visible, and older helmets may no longer meet current safety standards. Always buy new from a trusted dealer like Thunder Hill . Performance Questions How can I prevent helmet fogging?Use anti-fog visors like Bell’s DSAF system, or apply an anti-fog spray or insert. Keep vents open to maintain airflow inside the helmet during races. Why is ventilation important?Ventilation keeps you cool, reduces moisture inside the helmet, and helps prevent fatigue during intense sessions. A properly ventilated helmet helps you perform at your best. How do I store my helmet between races?Store it in a cool, dry place away from direct sunlight. Use a padded helmet bag—like the Thunder Hill Evo Helmet Bag—to prevent damage during storage or transport. Helmet Certification Questions What is the difference between Snell K2020 and CMR2016 certifications?Snell K2020 is for adult helmets, offering top-tier impact protection. CMR2016 is required for drivers under 15, with a lighter shell to reduce neck fatigue in younger racers. Are tear-off visors necessary?Yes. Tear-offs are a must-have for outdoor karting. They keep your visor clear by allowing you to quickly remove dirty outer layers while racing. How do I know if my helmet is still safe to use?Inspect it regularly for cracks, fading, and loose components. Replace it after any significant impact or every 5 years regardless of use. Never compromise on safety. Can I customize my helmet?Yes. Many brands—including Bell—offer customization options. However, never drill or alter the helmet shell, as it may void the warranty and compromise safety certifications. Where can I buy a certified kart racing helmet?Buy from trusted experts like Thunder Hill . Shop online or in-person at one of our retail locations across the USA. We carry all top brands including Arai, Bell, Stilo, and Schuberth—and support hundreds of race events nationwide.

Thunderhill is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline. Fits Chevy Corvette C6 Z06 (2005-2013) The GiroDisc system is an upgrade to a 2-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc. The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and Thunderhill RF-1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing 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 which is 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 8-10 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 2-piece GiroDisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.
