The Alcon Pro‑System front rotor assemblies for Porsche 981 Cayman GT4 are supplied as a pair and designed as direct replacements for the GT4 front braking system. These assemblies match the factory rotor dimensions and mounting for the Cayman GT4's front axle, helping maintain proper fitment and braking geometry for track or road use where front rotors need replacement.
