Product Description

The GiroDisc A2-224 Slotted Rear Rotor Rings are engineered to replace the OEM rear rotors on the 2016-2020 Alfa Romeo Giulia Quadrifoglio and 2016-2020 Maserati MC20 (without the Carbon Ceramic Brake option). This upgrade provides significant performance enhancements without the need for extensive modifications. The 2-piece design reduces unsprung weight and rotational mass, leading to improved acceleration and suspension response.

Constructed with high-carbon iron rotor rings and 6061-T6 aluminum hats, these rotors offer superior durability and heat dissipation. The curved vane design acts as a centrifugal pump, effectively cooling the rotors under hard use. The floating rotor system, featuring high-strength alloy steel drive pins, allows for thermal expansion while maintaining noise-free operation.

Designed for compatibility with stock calipers and ABS systems, the A2-224 rotors are a direct replacement that maintains factory brake bias and performance. Whether you're upgrading for street performance or track use, these rotors deliver the reliability and performance you demand.
