A1-111 Girodisc Two-Piece 398mm Front Brake Rotors (Discontinued Design) Fitment (FRONT): Ferrari 458 Italia Ferrari 488 Ferrari 488 Pista Ferrari F8 Discontinued New old stock rotor.  These have the straight grooves as images show, not the new curved grooves.  Final Sale, no returns or exchanges. Competition Motorsport 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 system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement1 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 traditional cast iron 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 Competition Motorsport RF-1 racing brake fluid, 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 braking 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. Sold/priced per pair. 1 Note: These Girodisc rotors have a different annulus (pad swept area) than the OEM CCM rotors, to maintain their light weight. A brake pad with an annulus of 66mm or less must be used with these Girodisc rotors. The necessary pad shape is very common, found on the Nissan GT-R, Cadillac CTS-V, and most AMG Mercedes equipped with six-piston calipers. If there's a specific pad and/or compound you're after please, contact us at (844) 438-7244 and we'll get you what you need!

C3 Carbon Ferrari F12 Carbon Fiber Engine Bay Panels When you open the hood of your F12, you see a beautiful 6.2L Ferrari V12 surrounded by dull-black plastic trim. Replace that trim with C3's autoclaved, pre-impregnated (pre-preg) dry 3k carbon fiber engine bay trim. Fit and finish are as perfect as the factory carbon pieces, bringsing the beauty of carbon fiber to your engine bay. C3 has matched the OEM Ferrari 1x1 weave for an original Ferrari appearance. Easy installation makes this a must-have for any F12 Berlinetta owner.

Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts. Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past. C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time. Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.

Kart Racing Helmet Frequently Asked Questions (FAQ) Remember that safety is paramount in kart racing, and choosing the right helmet and maintaining it properly is essential for your protection on the track. Consult the professionals at Competition Motorsport any time you have specific questions about your racing helmet. Why do I need a racing helmet?Auto and kart racing helmets are essential for protecting your head in high-speed accidents. They also shield against debris and, in some motorsports, fire—making them a non-negotiable safety requirement. How do I choose the right size Kart Racing helmet?Use a flexible tape to measure the circumference of your head just above your eyebrows and ears. Compare the measurement to the size chart. For more help, read our blog on how to fit your helmet properly at Competition Motorsport. Can I use a motorcycle helmet for kart racing?No. Motorcycle helmets lack the kart-specific certifications and features like proper ventilation and impact resistance optimized for karting. Always use a helmet rated for motorsport competition. How often should I replace my kart racing helmet?Replace your helmet every few years depending on usage and the manufacturer's guidance. If it’s been dropped, involved in an impact, or shows signs of wear, replace it immediately. Are expensive racing helmets safer than budget ones?Yes, typically. While both must meet minimum safety standards, premium helmets offer lighter materials, better fit, improved aerodynamics, and enhanced comfort, all of which impact race performance and fatigue. How do I maintain and clean my kart racing helmet?Clean the exterior and interior using a helmet-specific care product like the Molecule Helmet Care Kit. Avoid submerging the helmet or using abrasive cleaners. Visors should be cleaned gently to avoid scratching. Do I need to wear a balaclava under my kart racing helmet?While not required for all karting events, a balaclava enhances comfort, keeps your helmet liner clean, and helps wick sweat. Fire-rated balaclavas are mandatory in sanctioned auto racing and recommended for high-performance karting. Can I wear glasses with my kart racing helmet?Yes. Wide eye ports, make it compatible with most prescription glasses and racing eyewear. A good fit ensures the glasses remain stable and fog-free. Are carbon fiber helmets better?Carbon fiber helmets are lighter and stronger, reducing fatigue during long races while offering excellent impact protection. They are a top choice for competitive drivers. Can I use a used helmet for racing?It’s not recommended. Damage or degradation may not be visible, and older helmets might not meet current safety standards. Always buy new from an authorized dealer like Competition Motorsport. What's the importance of proper helmet ventilation?Good ventilation helps manage heat and moisture inside the helmet, reducing fatigue and keeping you focused throughout your race. How do I store my kart racing helmet between races?Store your helmet in a cool, dry place away from direct sunlight. Use a padded helmet bag like our Competition Motorsport Evo Helmet Bag to prevent damage during transport or storage. What is the difference between Snell K2025 and CMR2016 certifications? Snell K2025 is designed for adult karting helmets, focusing on impact protection. CMR2016 is tailored for drivers under 15, offering a lighter helmet to reduce neck strain while maintaining safety standards. Are tear-off visors necessary for kart racing? Tear-off visors are beneficial in maintaining clear vision during races by allowing drivers to remove a dirty visor layer quickly. They are especially useful in outdoor karting where debris and dirt are common. How do I know if my helmet is still safe to use? Helmets should be inspected regularly for signs of wear or damage. If a helmet has been involved in a significant impact or shows signs of degradation, it should be replaced immediately. Additionally, helmets should be replaced every 5 years, even if no damage is visible. Can I customize my kart racing helmet? Yes, many manufacturers offer customization options for fit and aesthetics. However, any modifications should not compromise the helmet's structural integrity or safety certifications.

Fire-rated balaclavas are mandatory in sanctioned auto racing and recommended for high-performance karting. Can I wear glasses with my kart racing helmet?Yes. Wide eye ports, make it compatible with most prescription glasses and racing eyewear. A good fit ensures the glasses remain stable and fog-free. Are carbon fiber helmets better?Carbon fiber helmets are lighter and stronger, reducing fatigue during long races while offering excellent impact protection. They are a top choice for competitive drivers. Can I use a used helmet for racing?It’s not recommended. Damage or degradation may not be visible, and older helmets might not meet current safety standards. Always buy new from an authorized dealer like Competition Motorsport. What's the importance of proper helmet ventilation?Good ventilation helps manage heat and moisture inside the helmet, reducing fatigue and keeping you focused throughout your race. How do I store my kart racing helmet between races?Store your helmet in a cool, dry place away from direct sunlight. Use a padded helmet bag like our Competition Motorsport Evo Helmet Bag to prevent damage during transport or storage. What is the difference between Snell K2020 and CMR2016 certifications? Snell K2020 is designed for adult karting helmets, focusing on impact protection. CMR2016 is tailored for drivers under 15, offering a lighter helmet to reduce neck strain while maintaining safety standards. Are tear-off visors necessary for kart racing? Tear-off visors are beneficial in maintaining clear vision during races by allowing drivers to remove a dirty visor layer quickly. They are especially useful in outdoor karting where debris and dirt are common. How do I know if my helmet is still safe to use? Helmets should be inspected regularly for signs of wear or damage. If a helmet has been involved in a significant impact or shows signs of degradation, it should be replaced immediately. Additionally, helmets should be replaced every 5 years, even if no damage is visible. Can I customize my kart racing helmet? Yes, many manufacturers offer customization options for fit and aesthetics. However, any modifications should not compromise the helmet's structural integrity or safety certifications.
