A1-308DS Girodisc Mercedes 360mm Front Rotors (Dimpled & Slotted)

These Girodisc A1-308DS 2-piece dimpled and slotted front rotors are a direct replacement for factory 360 mm front rotors on Mercedes performance models. The floating two-piece design reduces unsprung weight and improves cooling, while the surface pattern enhances pad bite and gas evacuation.
