Experience the Difference of C3 Carbon Products
Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. 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.

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 Competition Motorsport RF-1 brake fluid (available from Competition Motorsport), 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.

Girodisc A2-023 Rear Rotor FAQs:
Will these rotors fit McLaren models equipped with carbon ceramics? No. The A2-023 kit is designed for vehicles originally equipped with cast iron rotors. Carbon ceramic conversions require a different Girodisc setup.
How do these rotors improve performance? The two-piece design lowers unsprung weight, improves heat dissipation, and maintains consistent braking under heavy use, all while retaining OEM brake bias and control.
Do the curved vanes make a difference? Yes. The vane system acts as a centrifugal air pump, significantly improving airflow and cooling efficiency for reduced fade during extended high-temperature braking.
Are they noisy or prone to rattle? No. Girodisc’s anti-noise spring washer system prevents rattle while allowing the rotor to expand freely under heat, ensuring smooth and quiet operation.

Each Girodisc 2-piece assembly is a fully floating design that replaces the factory one-piece rotor to reduce unsprung and rotating mass. The 6061-T6 aluminum hats are CNC-machined and hard anodized for strength and corrosion resistance. The friction rings are machined from Girodisc’s proprietary high-carbon iron castings—developed for high thermal stability and superior resistance to cracking. The 48 curved internal vanes act as centrifugal pumps to pull cooling air through the rotor, keeping temperatures stable under aggressive braking.

Girodisc A1-001 Front or Rear Rotor FAQs:
Do these rotors fit both the front and rear axles? Yes. The A1-001 Girodisc rotors are designed for interchangeable use on either the front or rear of Ferrari 360 and F430 models without carbon-ceramic brakes.
Are these rotors lighter than stock? Absolutely. Each assembly weighs only 15.8 lbs, helping reduce unsprung and rotating mass for faster suspension response and improved handling.
Can the rotor rings be replaced? Yes. The aluminum hats are reusable, and replacement iron rings (P/N D1-001) are available when needed, reducing long-term maintenance cost.
Are these suitable for track use? Definitely. The curved vane cooling and floating design provide excellent thermal control and consistent braking even under extreme heat cycles.
Upgrade your Ferrari 360 or F430 with Girodisc two-piece rotors for unmatched stopping precision, reduced weight, and rebuildable performance worthy of Maranello’s finest.

Girodisc Ferrari 348 / F355 Front Rotors
The Girodisc system is a direct replacement for the factory front rotors on Ferrari 348 and F355 models. Designed as a high-performance alternative to OEM discs, these 2-piece floating assemblies weigh just 14.3 lbs per rotor—significantly reducing unsprung and rotational mass. This results in sharper handling, quicker suspension response, and improved braking control without affecting factory brake bias or ABS performance.
Advanced Construction
Each rotor ring is machined from Girodisc’s proprietary high-carbon iron alloy, developed for optimal strength, thermal stability, and durability under extreme conditions. The 30 curved directional vanes act as centrifugal pumps, pulling air through the hub to cool the rotors efficiently during heavy braking. The 6061-T6 aluminum hat is lightweight, anodized for corrosion resistance, and reusable—simply bolt new replacement rings (part number D1-002) when needed.

FAQs for Girodisc A1-002
Do these fit directly without modification? Yes. The Girodisc system bolts directly to the factory hubs and works seamlessly with OEM calipers and pads.
Can I replace only the iron rings? Yes. Girodisc rotors are fully rebuildable—when the rings wear out, you can replace them with new D1-002 rings and reuse the aluminum hats.
Are these rotors quieter than typical floating designs? Yes. Girodisc uses Belleville washers and spring clips to maintain proper float while eliminating unwanted noise or rattle during street driving.
Are they suitable for track and competition use? Absolutely. The high-carbon iron alloy and advanced vane design ensure superior heat dissipation and performance under extreme braking loads.
Upgrade your Ferrari 348 or F355 with Girodisc’s precision-engineered floating rotors—crafted in the USA for optimal cooling, reduced weight, and unparalleled braking performance on road or track.
