If you're looking to upgrade your braking system, the Girodisc setup is a solid choice. This isn’t just some off-the-shelf part; it’s a direct swap for the stock discs on your Ferrari 355, and you won’t need to fuss with any modifications. Just bolt it right on, and you’re good to go.
What really sets these rotors apart is the central hat section, crafted from U.S.-sourced 6061-T6 aluminum. That’s the same stuff they use in aircraft, so you know it’s tough. The rotor itself is made from Girodisc's proprietary cast iron, which is poured and machined right here in the USA. That means you’re getting quality control from start to finish.
The design features a curved vane system, which is pretty clever. It acts like a centrifugal pump, pushing cooling air through the disc to help manage heat during those spirited drives. Speaking of heat, the floating mount system is another standout feature. With 8 or 10 high-strength alloy steel drive pins, these rotors are designed to handle the load of braking while allowing for axial and radial float. That means they can move slightly, which helps avoid noise and wear.
Those pins are made right in the USA and are cadmium plated for corrosion resistance, so they’ll hold up over time. Plus, they’re secured with grade 12 cap screws and hardened washers to keep everything tight. To keep things quiet when you first start driving, Girodisc has included anti-noise spring washers. This setup allows the rotor to expand with heat but keeps it from rattling around when it’s cold.
When it’s time to replace the rotors, you won’t have to swap out the whole system—just pop in a new cast iron rotor, and you’re back in business. Each set is sold in pairs, so you’ll have everything you need for the front end of your Ferrari 355 or the Challenge version from ’94 to ’99.
If you want a braking upgrade that’s built to last and performs when it counts, the Girodisc rotors are worth a look.
