Brembo Porsche 981 Cayman GT4 Front Rotor Set (Excluding PCCB)

The Brembo 2-piece front rotor set for the Porsche 981 Cayman GT4 (excluding PCCB-equipped vehicles) is engineered as a direct upgrade for the factory braking system, offering improved thermal performance, durability, and consistency under aggressive driving conditions. Designed using motorsport-derived technology, these rotors enhance braking stability for both street and track use.

These 380x34mm 2-piece floating discs are designed to work with the OEM calipers, maintaining proper fitment while significantly improving heat dissipation and resistance to brake fade. The lightweight aluminum hat and high carbon alloy rotor ring combination reduces unsprung weight while increasing structural rigidity and braking efficiency.

The discs feature a corrosion-resistant finish along with Brembo’s floating D-bobbin mounting system with anti-rattle hardware. Combined with a vented curved 72 vane internal ventilation design, the system is optimized for effective heat management and consistent braking performance under repeated high-load conditions.
