Girodisc Alfa Romeo 4C Front Rotors
The Girodisc front rotors for the Alfa Romeo 4C are precision-engineered to improve braking performance while maintaining perfect factory fitment. Designed as a direct replacement for the OEM rotors, these lightweight two-piece discs deliver faster response, cooler operating temperatures, and reduced rotational mass for sharper handling and braking consistency both on the street and track.
Lightweight. Efficient. Built for the 4C.
The central hat section of each rotor is made from U.S.-sourced 6061-T6 aircraft-grade aluminum for superior strength with minimal weight. Girodisc’s proprietary cast-iron rings are poured and machined in-house, using a curved vane design developed in racing to act as a centrifugal pump—drawing air through the disc for maximum cooling efficiency. The result is a fade-resistant braking system that enhances pedal feel and control.

FAQs: Girodisc Alfa Romeo 4C Front Rotors
Do these rotors require any modifications? No, they bolt directly to the factory calipers and hubs with no spacers or adapters required.
Are they suitable for track use? Yes, Girodisc rotors are designed to handle repeated high-temperature cycles and heavy braking loads typical of track environments.
What are they made of? The rotor hat is CNC-machined from 6061-T6 aluminum, and the rotor ring is Girodisc’s proprietary high-carbon cast iron for superior heat dissipation.
Can I replace just the rotor rings later? Absolutely — the Girodisc system is fully rebuildable. Replacement rings are available separately when the originals wear out.
