Girodisc Ford S550 Mustang GT350 Front Rotor Rings Fitting your Ford Mustang S550 Shelby GT350, the GiroDisc D1-162 is the direct replacement for your Girodisc A1-162 brake kit. This complete kit consists of 2 rotors and new hardware. You will re-use your Girodisc hats and bring your braking feel back to new. Girodisc GT350 Front Rotor Rings Details: Manufacturer: Giro Disc Manufacturer Part Number: D1-162 Surface: Slotted Material: Steel Intended for Street/Track Use: Yes For Use with Stock Calipers: Yes Rotor Construction: Vented Rotor Style: Slotted surface Rotor Material: Iron Rotor Finish: Black E-coat Quantity: Sold pair (one axle set) Girodisc GT350 - Front Rotor Rings Fitment: 2016-2020 Ford Shelby GT350 (S550) w/ Girodisc Rotor Hats 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 central hat section of Girodisc's rotor is made from the strictly U.S. 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 48 curved directional vanes, 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 their own specifications and cadmium plated for 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 class 12.9 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. Girodisc Advantages:GiroDisc brake kits are seen at every track weekend on very exotic and extreme track cars. What made GiroDisc owners leave their OEM rotors and upgrade to a 2 piece GiroDisc kit? Less Rotating Mass via 2 piece design Lightweight 6061-T6 Aluminum Hat Grade 12 floating hardware to allow the rotor to grow when heated Curved vane design creates a cooler rotor Significant cost reduction compared to OEM GiroDisc Rotor Hat:The GiroDisc front central is manufactured using aircraft grade 6061-T6 aluminum. Less weight creates a huge advantage in acceleration and braking. Anyone who has spent the money on a lightweight double-disk clutch kit with aluminum flywheel knows the importance of rotating mass. Using a lightweight rotor kit allows the brakes to decelerate the vehicle, not the rotor. GiroDisc Floating Rotor Ring:Quality hi-carbon cast iron is the foundation of every GiroDisc brake rotor. Every rotor ring is made carefully in house at the GiroDisc factory in Washington state. The GiroDisc rotor utilizes a curved vane design that was originally developed in racing to act as a centrifugal air pump to force cooling air from the center of the rotor ring to the outside. This principle is similar to what is know as a squirrel cage fan design. By having impellers (vanes) between the two rotor faces, the air is moved radially, from the center outward, changing the direction of the airflow and increasing velocity. This design is mechanically strong, reliable, and very effective. GiroDisc Rotor Ring Hardware:The GiroDisc rotor ring and light-weight aluminum hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for long-lasting corrosion resistance. These drive pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The drive 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.GiroDisc Rotor Ring Replacement:Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Your GiroDisc replacement rotor rings come complete with 2 new rotor rings and all required floating rotor hardware. This is a very simple task that is quite fun. The aluminum rotor hat usually does not ever need replacement unless bent or damaged. If you damaged has reached your GiroDisc hat, you likely have more than a few other things to replace also. The hat is rugged and overly strong.

INCLUDES TWO REPLACEMENT ROTOR RINGS AND ASSOCIATED HARDWARE.

IPD Competition Plenum for Porsche 997.1 Carrera/Carrera S The IPD "Y" design plenum replaces the factory "T" style air distributor and provides substantial power and torque gains by means of a more efficient design. Horsepower gains range from 24 to 28 depending on engine displacement and engine condition. These max power gains are experienced in the mid range where is it most useable and enjoyed. The IPD plenum not only delivers impressive power and torque increases but also creates a more linear power and torque band. Tiptronic customers even claim considerable improvements with more positive shifting after installing the IPD Plenums. Porsche has been controlling engine output by restricting the inlet track for decades. This has been successfully accomplished by utilizing smaller throttle bodies. This simple power control solution has been a very effective way of preventing lower level models from out performing certain flagship models, especially models with prolific racing pedigree. Although the factory engine packages are fantastic performance machines, they are engineered and developed to achieve specific performance numbers that satisfy a target demographic and compete with rival brands. Unfortunately driving enthusiasts who seek an elevated Porsche driving experience require performance levels well outside the target market. IPD Plenums deliver substantial power and torque gains, but when combined with larger throttle bodies they perform even better. All of the IPD "Competition" Plenums utilize the next largest size throttle body offered by Porsche. In this case, the Competition Plenum does away with your original 74mm throttle body in favor of Porsche's 82mm 997 GT3 throttle body (can be added above). All of our Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque. IPD has pioneered another new Plenum design with the Competition Carrera Plenum. Laminar flows and volumetric efficiencies have been further enhanced with our unique and innovative internal merge collector area. This completely new approach has yielded not only great performance gains but more linear power delivery and improved throttle response as well. Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all "should" know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. IPD tests and evaluates all products on bone stock cars, this establishes a level playing field and a better "apples to apples" comparison. The Competition Carrera Plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile. Power improvements will be fully realized once the factory ECU/DME makes all the necessary "adaptation" requirements. This process can be expedited with a series of "hard pulls" or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit. This plenum requires a Bosch 82mm throttle body, which can be added to your order above for only $225 (save $100).

The D2-145 is the replacement rotor ring kit for the Girodisc A2-145 two-piece steel rotor and aluminum hat combination. It includes all necessary hardware to replace both rear rotor rings. We recommend using the Pagid 2487 racing brake pad with this Girodisc system. As an authorized Girodisc dealer with one of the largest inventories in the country, we ship products within one business day to ensure we meet your delivery deadline. CONTAINS TWO REPLACEMENT ROTOR RINGS AND ASSOCIATED HARDWARE.

FITMENT (REAR): Ford Shelby GT500 (2007-12) Ford Mustang BOSS 302(S) Ford Mustang GT (2011-14 w/ Brembo calipers) 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. This Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination as a direct replacement for the OEM brake discs. The Girodisc floating rotors will bolt directly to your Mustang and work flawlessly with OEM calipers. 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 effectiveness and efficiency. The Girodisc rotors are lighter than OEM pieces, resuutling in a reduction in rotational and unsprung weight (4 lbs per corner) allowing for quicker acceleration, stronger braking, and faster suspension response. When used with Pagid or PFC performance brake pads, and Discovery Parts RF-1 brake fluid, you have the best possible 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 rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

It is a good idea to take several measurements to make sure you have the largest one. The ARAI GP-5W helmet will ship to you with signature required for delivery. 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?

We ship most products same or next business day to ensure we meet your delivery deadline.   Our replacement rings are sold in pairs and include replacement hardware. The only parts you will reuse are your existing GiroDisc hats. Please note that unless specifically noted, GiroDisc replacement rings are only designed to work with GiroDisc hats. They are not designed to be used with other brands, including hats from cars equipped with 2-piece rotors from the factory. We recommend replacing the rotor rings when they reach a minimum thickness of 22mm or if a crack extends to the edge of the ring. These rotors are sold and priced per pair.
