Product Description

The GiroDisc A2-282 370mm slotted rear rotors are engineered to enhance the braking performance of your 2021-2025 BMW G8X series, including the G80 M3, G82/83 M4, and G87 M2. These rotors feature a 2-piece floating design that reduces unsprung weight, improving acceleration and suspension response. The high-carbon alloy rotor rings are equipped with 72 curved internal vanes that act as a centrifugal pump, effectively cooling the rotors under hard use.

Manufactured in the USA, the rotors utilize lightweight anodized 6061-T6 aluminum hats and are fully compatible with factory calipers and brake pads, requiring no modifications for installation. The reusable hats can be paired with D2-282 replacement rings when needed, offering cost-effective maintenance. Whether you're engaging in spirited street driving or track sessions, these rotors provide superior heat dissipation and consistent braking performance.
