GiroDisc 2021+ BMW M2/M3/M4 (G8X Excl CCM) Slotted Front Rotors

The GiroDisc Slotted Front Rotors for 2021+ BMW M2, M3, and M4 (G8X excluding Carbon Ceramic Models) are crafted to deliver exceptional braking performance tailored to high-demand driving scenarios. Constructed from premium high-carbon iron, these rotors efficiently dissipate heat and resist wear, helping to minimize brake fade during aggressive driving or track use. The slotted surface ensures continuous removal of brake dust, gases, and debris, maintaining optimal pad contact and consistent braking power.

Designed as a two-piece floating rotor system, these rotors combine durable iron rings with lightweight aluminum hats to reduce unsprung weight and rotational inertia. This configuration improves brake responsiveness and vehicle handling while accommodating thermal expansion to prevent warping or noise. GiroDisc’s slotted front rotors offer a direct bolt-on upgrade that enhances the BMW G8X braking system, balancing race-level capability with street-ready smoothness.
