A1-308 Girodisc Mercedes 360mm Front Rotors FAQs:

Do these rotors require new calipers or brackets? No. They bolt to the factory hubs and work with OEM calipers and pads on the listed applications.

Are they directional? Yes. Each rotor has directional internal vanes; install left/right as marked to ensure proper airflow.

What pads are recommended? They are compatible with OEM pads and popular street/track compounds (e.g., Ferodo DS1.11, Pagid, Hawk). Bed-in per the pad manufacturer.

How do they compare to OE one-piece discs? Lower rotating mass and better heat rejection reduce fade and can improve response on track.
