GiroDisc 2021+ BMW M2/M3/M4 G8X 370mm Slotted Rear Rotors

The GiroDisc 370mm Slotted Rear Rotors for the 2021+ BMW M2, M3, and M4 G8X models are engineered to provide outstanding braking performance for both aggressive street driving and track applications. Constructed from high-carbon iron, these rotors excel at dissipating heat efficiently, minimizing brake fade during sustained heavy braking. The slotted surface promotes continuous cleaning of brake pads by removing dust, gases, and debris, ensuring consistent friction and confident stopping power when it matters most.

These rotors are designed as part of a two-piece system featuring lightweight aluminum hats and a floating mount design that reduces unsprung weight and rotational mass. This setup enhances vehicle handling and responsiveness while allowing for thermal expansion without warping or noise. GiroDisc’s precision-manufactured slotted rear rotors offer a direct bolt-on upgrade that maintains OEM compatibility, delivering race-quality durability and improved pedal feel without compromising daily driving comfort.
