Product Description

The GiroDisc A1-282 Front Slotted Brake Rotors are engineered to enhance the braking performance of the 2021 and newer BMW G8X M2, M3, and M4 models equipped with 380mm iron rotors. Designed as a direct replacement for the OEM rotors, these two-piece rotors feature lightweight 6061-T6 aluminum hats and high-carbon cast iron rotor rings. This construction not only reduces unsprung weight but also improves heat dissipation, leading to more consistent braking performance under aggressive driving conditions.

The slotted surface design aids in pad bite and gas evacuation, ensuring optimal contact between the brake pads and rotor surface. These rotors are compatible with the factory calipers and maintain the vehicle's original brake bias and ABS calibration, eliminating the need for additional modifications. Precision-machined in-house, the A1-282 rotors offer consistent quality and performance. Sold as a pair, they are a straightforward upgrade for BMW enthusiasts seeking improved braking capabilities without compromising on OEM fitment.
