The GiroDisc slotted front ring for Porsche 911 GT3 Cup (997) is a direct-fit replacement ring matched to that model's front brake assembly. Intended as a service or track-focused refresh, the slotted surface renews the rotor contact face to help evacuate pad residue and maintain predictable pad engagement during repeated high-demand braking cycles.
