Ferrari 398mm Front Rotors
Girodisc 398mm front rotors bring race-level braking performance to your Ferrari, replacing the stock carbon-ceramic setup with a durable, serviceable iron system. Designed as a direct-fit solution, these rotors require no modifications and work seamlessly with the factory calipers once fitted with brake pads that feature a 66mm swept area or less. The result is a lighter, cooler-running system that delivers exceptional pedal feel and fade resistance on both street and track.
Each Girodisc rotor is crafted in the USA using a combination of 6061-T6 aluminum hats and proprietary high-carbon cast-iron rings. The internal curved vane design actively pumps air through the rotor to dissipate heat under extreme braking, ensuring consistent performance lap after lap.

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.

Upgrade your Audi B8 S4 or S5 with Girodisc 2-piece floating rotors for reduced unsprung weight, improved cooling, and OEM-level fitment. These precision-engineered replacements bolt directly to your car without modifications, maintaining perfect compatibility with factory calipers, brake bias, and ABS. Each rotor sheds over 4 lbs compared to stock — 19.1 lbs versus 23.6 lbs — for faster suspension response and sharper acceleration.
These rotors also fit B8 A4, S4, and S5 models upgraded with the four-piston Brembo caliper from the Q5 3.0T, making them a versatile performance upgrade across the Audi platform. Whether you’re carving canyons or pushing hard on track, Girodisc delivers cooler, quieter, and more consistent braking.

Ferrari F430 Front Iron Rotor Conversion
Upgrade your Ferrari F430 with Girodisc’s Front Iron Rotor Conversion — a direct bolt-on replacement for the OEM carbon-ceramic rotors. This setup maintains your factory brake balance, ABS tuning, and pedal feel while improving heat control and reducing long-term maintenance costs. Designed for both street and track use, these rotors provide consistent performance without the fragility or expense of CCM components.
To optimize performance and control weight, these rotors require brake pads with an annulus (swept area) of 66mm or less. Girodisc recommends the same pad shapes used on popular performance platforms such as the Nissan GT-R, Cadillac CTS-V, and AMG Mercedes with six-piston calipers. This makes sourcing replacement pads simple and affordable while maintaining exceptional braking response.
