Simpson Hybrid S 3-Point Head and Neck Restraint The Hybrid S Head Restraint is FIA and SFI approved (when worn with a multi-point harness system) and is tested and shown to be compatible with 3-point harnesses used by Car Club enthusiasts and High Performance Driving Experiences. This allows Driving Instructors, Auto Manufacturing Test Engineers, and others in cars with 3-point harnesses to have added protection. We are pleased to offer this great option for increased protection to this sector of the market. Bear in mind, however, that on a racetrack the best protection we believe is a Full-Containment Cockpit System that includes a full containment seat, Snell SA2015 or FIA 8860 rated helmet, FIA or SFI approved head restraint, and 6- or 7-point racing harness system. SIMPSON HYBRID S 3-POINT HNR OPTIONS Select your size based on the size chart DiscoveryParts only carries this device with standard HANS post anchor clips as they're lightweight and easy to attach/detach SIMPSON HYBRID S 3-POINT HNR FEATURES FIA and SFI Approved with 5-, 6- and 7-point harness systems FMVSS Tested for use with 3-point OEM belt system High quality carbon fiber construction Low profile, no high back to hook on the roll bars, etc. in emergency exit Multiple load paths to dissipate head loads Buckle attachment in front, no bulky straps underneath SIMPSON HYBRID S 3-POINT HNR INSTALLATION To use a Hybrid S with a 3-point seat belt system, the SAS (Seatbelt Anchoring System) is not used. (The SAS strap anchor loops hook into the buckle of a 5-, 6- or 7-point racing harness.) Have the wearer put on the Hybrid S and get into the driver's seat. Follow the instructions on fitting the device to the wearer. Engage the 3-point seat belt and sit in the normal driving position. Have a helper apply gentle pressure to the top of the device, keeping the device stable during tether adjustment. The device should be in a comfortable position behind the driver back, against the seat cushion. With the helper holding the device and the driver looking straight forward, hold the triangulated tether up to the anchors on the driver helmet. Adjust the side tethers so that the end fitting can be easily inserted into the helmet anchor without pulling down on the helmet. A comfortable adjustment on the side tether is to have about 1" of slack in the tethers. With the helper still holding the device down and the driver looking straight ahead, adjust the rear tethers so that there is 1"to 1.5" of slack. Test the amount of head movement by moving the head straight forward. The driver should have 1" to 2" of forward head movement before the slack is taken out of the tether. Remember when checking this not to rotate the head down; translate it straight forward. This should allow for plenty of head movement on track. AIRBAG USE WITH SIMPSON HYBRID S 3-POINT HNR No one should unhook or disable the airbag system installed by the auto manufacturer or their authorized installer. Outside experts in Detroit have confirmed this and require their test engineers to use the Hybrid S in conjunction with the airbag in a 3-point system. Simpson agrees that the airbag and Hybrid S work together to increase protection in frontal crashes.

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. The Stilo WRC Venti Range Composite helmet will ship with signature required for delivery. STILO WRC VENTI COMPOSITE HELMET FREQUENTLY ASKED QUESTIONS (FAQ): Remember that safety is paramount in auto racing, and choosing the right helmet and maintaining it properly is essential for your protection on the track. Always consult with the professionals at Discovery Parts and refer to the manufacturer's guidelines for specific questions about your racing helmet. Why do I need a racing helmet? Auto racing helmets are designed to protect drivers from head injuries and fire during high-speed races and crashes. They are a crucial safety component in motorsports. How do I choose the right size helmet? You should measure your head's circumference using a flexible tape measure, then refer to the manufacturer's sizing chart to select the appropriate size helmet. Please review our blog posting on how to properly fit your new auto racing helmet from Discovery Parts. What safety standards should I look for in a racing helmet? Look for helmets that meet safety standards like Snell and FIA depending on your racing discipline. These standards ensure the helmet's safety and quality. DOT helmets are designed for street use and not for racing and track use. What's the difference between full-face and open-face, and helmets? Full-face helmets provide the most protection with a complete face shield, while open-face helmets cover the top and sides of the head. Can I use a motorcycle helmet for auto racing? No, motorcycle helmets do not provide the same level of protection as auto racing helmets, as they are designed for different purposes. It's recommended to use a helmet specifically designed for auto racing which includes fire protection in addition to impact protection. How often should I replace my auto racing helmet? Auto racing helmets should be replaced every 5-10 years, depending on the manufacturer's recommendations and usage. If the helmet is involved in a crash, it should be replaced immediately. Are expensive racing helmets safer than budget ones? Safety standards dictate the minimum safety requirements, so even budget-friendly helmets can offer protection. However it’s important to consider how lower-priced helmets are meeting the required testing standards. More expensive helmets are lighter, smaller, are constructed of superior materials, and often come with additional features then less expensive helmets. How do I maintain and clean my racing helmet? Follow the manufacturer's instructions for cleaning and maintenance. You should clean the exterior, interior and shield with the Molecule Helmet Care Kit. Do I need to wear a balaclava under my racing helmet? Balaclavas are typically not required for Driver's Education events, however they make wearing a helmet much, much more comfortable. Balaclavas will provide fire protection (if fire rated), help keep your helmet lining clean and order free by absorbing the majority of sweat while using it, and additionally balaclavas make putting your helmet on and taking it off by protecting your ears and keeping from from folding over when you helmet is worn. Discovery Parts recommends balaclavas from Alpinestars, OMP, Sabelt, Sparco, and Stand21. If you are entering sanctioned auto racing events, balaclavas will be required for fire protection. Is the SNELL SA Rating important? The Snell SA2020 certification is a safety standard established by the Snell Memorial Foundation for auto racing helmets. It sets the criteria and requirements that helmets must meet to be considered safe and suitable for use in motorsport events. Snell SA2020 certification is highly regarded in the motorsports industry and is often required or recommended by racing organizations and events. It signifies that a helmet has passed rigorous testing to provide maximum safety for drivers in various motorsport disciplines, including road racing, NASCAR, Formula 1, drag racing, and more. It's essential for drivers to check the specific safety standards required by the racing organizations they participate in to ensure compliance. Is the FIA helmet certification important? Yes, FIA (Fédération Internationale de l'Automobile) certification is crucial for auto racing helmets, especially in the context of international motorsport events and many national and regional racing series in the USA. The FIA 8859-2015 standard is commonly associated with racing helmets used in various motorsport disciplines. Helmets certified to FIA 8859-2015 met the safety requirements set by the FIA and were widely accepted in many racing series Which helmet certification is the most stringent and the hardest to meet? The FIA 8860-2018 certification is considered the most stringent and advanced helmet certifications available for auto racing helmets, and it is often associated with top-tier motorsport categories like Formula 1. It's important to note that the FIA 8860-2018 helmets offer a high level of protection and their use is mandatory in many racing series. Drivers should always check the regulations of the racing series they intend to participate in to ensure compliance with helmet certification standards. Can I wear glasses with my helmet? Most helmets have provisions for wearing glasses or goggles, but check the design to be sure. Most manufacturers feature helmet models with wider eye ports to better accommodate eye glasses. Are carbon fiber helmets better? Carbon fiber helmets are lightweight and strong, a top choice for racers. But remember, certification matters most. Can I use a used helmet for racing? It's best to buy a new helmet. Used helmets may have unseen damage or be out of date on safety standards. Can I buy replacement parts for my helmet, like visors or padding? Many manufacturers offer replacement parts, including visors and padding, to extend your helmet's lifespan. How can I prevent helmet fogging during races? Anti-fog sprays and inserts are available to help keep your visor clear during races. What's the importance of proper helmet ventilation? Proper ventilation helps keep you cool and comfortable during races, reducing the risk of heat exhaustion. How do I store my helmet between races? Keep it in a cool, dry place away from direct sunlight and chemicals in a bag designed to store your auto racing helmet, like the Discovery Parts Evo Helmet Bag. Where can I buy a certified racing helmet? You should only buy from a professional authorized dealer who has sold thousands of helmets. You can find all the best brands at Discovery Parts online at www.discoveryparts.com or visit our retail store at Atlanta Motorsports park or at one of the hundreds of race and track day events we attend and support.

Discovery Parts is an authorized dealer for Girodisc products and 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.   Introducing the GiroDisc 2-piece rotors, designed as a direct replacement for the E46 M3 345mm rotors found on Competition Package (ZCP) and CSL models. Each rotor assembly weighs 17.5 lbs compared to the factory rotors' 19 lbs, significantly reducing unsprung weight and rotating mass on the front axle. Our rotor rings are machined from a proprietary high-carbon iron casting, formulated to GiroDisc's exacting specifications. This superior metallurgy ensures enhanced durability, while the 48 curved vanes act as a centrifugal pump, efficiently cooling the rotors during rigorous use. The innovative 2-piece design features a reusable hat that can be easily attached to new rings (part number D1-012) when replacement is needed. All key components, including hats, rotor rings, and drive pins, are manufactured in-house at our Bellingham, WA facility using domestically sourced materials. The hat is crafted from 6061-T6 aluminum with a black anodized finish. Drive pins, made from a high-strength steel alloy, are cadmium-plated for superior corrosion resistance. Each rotor assembly incorporates spring clips and Belleville washers, ensuring race-ready float while remaining street-friendly without noise from loose hardware. Our E46 M3 rotors are compatible with common aftermarket caliper setups, including Brembo calipers from both Porsche 996 and Megane RS swaps, in addition to the stock sliding calipers available on ZCP and CSL models. **Specifications:**- Diameter: 345mm- Thickness: 28mm- Weight: 17.5 lbs per rotor assembly We recommend replacing the rotor rings when the thickness reaches 26mm or if a crack extends to the edge of the ring. Priced and sold per pair.

FITS: Lamborghini Huracan Super Trofeo ONLY REPLACEMENT ROTOR DISCS ONLY, DOES NOT INCLUDE ALUMINUM HAT. Discovery Parts 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. The GiroDisc replacement rotor system is a direct rotor disc replacement for the OEM 2-piece hat and rotor and no modifications are necessary. 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 grade 12 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 to minimize replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.

As one of the largest stocking dealers in the country, we ship most Girodisc products the same or next business day to ensure we meet your delivery deadline. Fits Chevrolet Camaro ZL1 Gen 5 The Girodisc system is a direct replacement for the OE disc, they will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The central hat section of the Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's 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 forcing cool air through the disc. The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads. Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats. Sold/priced per pair

The two-piece Girodisc design allows for rotor ring-only replacement to minimize replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

FITMENT (FRONT): Audi 8V RS3 Discovery Parts is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. We ship most Girodisc systems the same or next business day to ensure we meet your delivery deadline. The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Girodisc front rotors are approx 22.0lbs vs. 27.4lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. 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.
