The Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake rotors. These two-piece floating rotors will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight, high-performance replacements (as opposed to a big brake kit), your factory brake bias is maintained, along with your ABS efficiency.
Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response.
When used with Pagid or PFC performance brake pads, and RF-1 brake fluid (available from ), 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 constructed in the USA, 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 their 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 two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.

The Arai GP-5W Auto Racing Helmet: Your Ticket to the VIP Racing Experience
Welcome to the next-gen of auto racing helmets, where style and substance join forces to deliver a turbocharged head-hugging experience. Introducing the Arai GP5W. Forget what you know about racing helmets because the GP-5W is rewriting the rules, one lap at a time!
Let's start with that drop-dead gorgeous, wider 90mm eye port opening. Not only does it make you look like you’re straight out of a futuristic racing movie, but that approx 3.5” top-to-bottom view? It's like watching the racetrack on IMAX. This isn’t just any window to the track; it's your panoramic penthouse view of the racing world.
Now, we've all had those moments, squinting through standard visors, missing out on the beauty of the track’s curves. No more! The exclusive shield on the GP-5W flaunts that larger opening, ensuring every twist and turn is yours to conquer.
Safety? The Arai GP-5W doesn’t just talk the talk; it revs the engine and roars. Snell SA2020 certified? Check. Factory-installed M6 washer/nuts? You bet. So, when it comes to anchoring your Head and Neck Restraint system, it’s smooth sailing (or should we say, smooth racing?). Plus, that cherry-on-top FIA 8859-2015 certification sticker nestled on the shell interior lining is just the nod from the pros you’ve been waiting for.
So, if you're the kind of racer who demands the best, whether you're tearing it up in stock car showdowns, pushing limits in a club race, or getting gritty with rally drives, the Arai GP-5W is your helmet soulmate.
The Arai Auto Racing GP-5W SA2020 Helmet is perfect for stock car, road race, and rally drivers. The GP-5W Helmet is a favorite because of its wider, 90mm (approx 3.5 top to bottom) eye port opening. The GP-5W uses its own exclusive shield with this larger opening.
The Arai GP-5W is Snell SA2020 certified with M6 washer/nuts installed at the factory. Drivers of any experience level will be able to easily install their Head and Neck Restraint system anchor posts (sold separately). The Arai Auto Racing GP-5W SA2020 also comes with the FIA 8859-2015 certification sticker found on the shell interior lining.
SCLC CONSTRUCTION
The GP-5W Helmet SA2020 is built with Arai's exclusive, very-lightweight SCLC (Super Complex Laminate Construction) shell technology. This ensures a low overall weight to balance the added weight of the helmet larger shield.
ARAI GP-5W SHELL SHAPE
The The Arai Auto Racing GP-5W Helmet SA2020 helps reduce fatigue for the driver due to its more natural head shape, smaller shell size, and lower center of gravity to assist with balance and stability.
ARAI GP-5W INTERIOR FIT
The The Arai Auto Racing GP-5W Helmet SA2020 is designed to closely match the shape of the human head, allowing for a snug, yet comfortable, fit. Arai has developed this natural shape over more than 50 years of helmet design research and refinement.
ARAI GP-5W WIDER EYE PORT
Sedan drivers will appreciate the larger, 90mm eye port, top to bottom. A visor peak is available for drivers not needing a shield on the The Arai Auto Racing GP-5W Helmet SA2020.
REMOVABLE/REPLACEABLE CHEEK PADS
Low-maintenance, easy-to-clean cheek pads are removable, washable, and replaceable with pads of varying thickness to provide a snug, safe fit.
M6 ANCHORS
The FIA-8859-2015 certified ARAI GP-5W Helmet SA2020 is pre-installed with the M6 threaded washer/nut with 6mm threads. This convenient feature allows the driver to use the anchor system that works with their Head and Neck Restraints the best. The anchor post is made to rest flush on the helmet surface due to a flat surface area around the mounting nut. Accepts a variety of anchor systems for Head and Neck Restraints.
ARAI GP-5W VENTILATION
Sedan car and closed cockpit drivers need greater airflow when racing. The upper ventilation system of the ARAI GP-5W SA2020 Helmet incorporates two exhaust vents and two large intake ducts to help keep the driver cool and comfortable.
OPTIONS INCLUDE
Anti- Fog Shields in Clear, Light Tint and Dark Smoke; Standard shields in Clear, Light Tint and Dark Smoke.
An effective helmet is one that fits properly. Have an assistant use a measuring tape, or a piece of string to measure the circumference of your head starting at a point approximately one inch above the eyebrows in front, around a point in the back of the head that results in the largest possible measurement, and finally wrapping back to the front. It is a good idea to take several measurements to make sure you have the largest one.

ARAI GP-5W 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 Arai GP-5W Auto Racing 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 Arai GP-5W 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 Arai GP-5W Auto 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 Arai GP-5W Auto 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 Arai GP-5W Auto Racing 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 Arai GP-5W Auto Racing 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 Arai GP-5W Auto Racing 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.

Chevrolet C8 & C7 Corvette, Cadillac CTS-V, and Camaro G5 and G6 racing brake pads in the Ferodo DS3.12 track only compound. The Ferodo 3133G DS3.12 brake pad has the flattest torque curve across the largest temperature range with very high torque for repeatable stops, lap after lap.
Ferodo FRP3133G DS3.12 Details:
Manufacturer: Ferodo
Manufacturer part number: 11 FRP 3133G-N
Primary Use: Endurance Race
Application: Downforce Touring Car, Extreme GT, Time Atack
Highest friction coefficient and bite in the Ferodo Racing range
Reproducible and stable performance up to 850 C under all pressure and speed conditions
Excellent management of ABS during the brake event
Longest pad life of Ferodo Racing range under heavy duty track use
Recommended for track use on larger vehicles with ABS
Ferodo DS3.12 Brake Compound Details:
The Ferodo DS3.12 is a track only compound with the flattest torque curve across the largest temperature range with very high torque. The Ferodo DS3.12 is identified with production code "G" and is the latest evolution in the Ferodo's DS track-only brake pad line. Designed for Hyper, Super and modern sports cars that have increased horsepower, more aero, higher curb weight, and stickier tires.These attributes all place greater demands on the vehicle’s ABS system.
The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands. Out of all the pad compounds we have ever tested, even from manufacturers, the DS3.12 shows the flattest torque curve across the broadest temperature range. That means that on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same, providing tremendous consistency and repeatability.
The DS3.12 has a higher mu than all of Ferodo’s other compounds, so not as much leg pressure is required to initiate the desired response. It is also unfadable, showing no drop in performance at any temp your brakes will ever see. In dyno testing, the DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to the discs. We believe the DS3.12 will become the gold standard to which other race compounds will be compared.

Bedding the brake components requires good concentration, experience and a lot of training time. But time is often crucial and you need to save it for other purposes.
Incorrectly bedded brakes reduce the controllability and the lifetime of the pads and discs. The maximum braking performance can only be achieved by correctly bedded brake parts.
To save time and money, we offer pre-bedding brake pads via a computer controlled system. Using the right sensory input, we can precisely bed in your pads free from environmental influences like traffic, rain, and even driver training.
Pagid RSL 1 Compound
Used in GT cars, touring cars and prototype endurance racing. Due to the high friction and good modulation, often used in sprint races as well. RSL 1 is a low metallic resin bonded material containing steel and aramid fibers with very high heat resistance. It maintains a constant friction level over a wide range of temperatures. Its reduced wear rate and disc friendliness make this material appropriate for endurance races.
Pagid RSL 1E Compound:
RSL 1E is perfect as front axle application for long endurance GT and touring car racing. RSL 1E and RSL 1 are low metallic resin bonded materials containing steel and aramid fibers with very high heat resistance. They maintain a constant friction level over a wide range of temperatures. Their reduced wear rate and disc friendliness make these materials appropriate for endurance races.
RSL 1E is further improved in terms of pad life and modulation as well as friction stability at high temperatures and pad life. As a benefit, RSL 1E provides the lowest pad wear rate in the PAGID Racing portfolio for highly thermally loaded applications.
Pagid RSL 2 Compound:
RSL 2 is a low metallic resin bonded material containing steel and aramid fibers with high heat resistance. It maintains a constant friction level over a wide range of temperatures. Its reduced wear rate and disc friendliness make this material appropriate for endurance races on applications with high cooling efficiency. RSL 2 features excellent pad life and modulation, as well as friction stability at high temperatures.
Applications include GT cars, touring cars and prototype endurance racing. Due to excellent modulation characteristics, RSL 2 is often also used in sprint races.
Pagid RST 1 Compound
Used in Rally tarmac, GT cars and touring cars circuit racing (sprint), high down-force formula cars, NASCAR. Suitable for applications in heavy cars and where high torque is necessary against small diameter rotors. RST 1 has a very high friction level and high temperature resistance. It is a semi-metallic resin bonded material containing steel fibers. Cold friction and initial bite makes this material most appropriate for Rally and NASCAR applications.

FITS: CHEVROLET CORVETTE WITH Z06 PACKAGE (2023-)
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 Giro Disc 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.
