BMW F8X M2 / M3 / M4 400mm Front Rotors
Upgrade your BMW’s stopping power with Girodisc 400mm 2-piece floating front rotors for the F8X M2, M3, and M4. Designed as a direct bolt-on replacement for factory discs, these rotors require no modifications and work flawlessly with OEM calipers. Lighter, stronger, and more thermally efficient than stock, they transform your braking consistency and control on both street and track.
Precision Performance Meets German Engineering
Each Girodisc rotor is crafted in the USA from motorsport-grade materials to meet the demands of high-performance BMWs. The hat is CNC-machined from 6061-T6 aluminum to reduce weight and unsprung mass, while the cast-iron rotor rings are made from Girodisc’s proprietary high-carbon alloy. Internal curved vanes act as centrifugal pumps, pulling air through the rotor to keep braking temperatures stable during spirited driving and heavy track sessions.
