Girodisc 2-Piece Rear Brake Rotors for 981/718 Cayman (PCCB Turbo Caliper) – 390 mm

Upgrade your Porsche’s braking performance with the Girodisc A2-394 2-piece rear rotor set. Designed to bolt directly in place of the PCCB carbon-ceramic discs, these rotors reduce unsprung weight, improve thermal stability, and deliver reliable track and road performance.

A2-035 Vehicle fitment

• Porsche 981 / 718 Cayman with PCCB Turbo Caliper (rear axle).
• Compatible with 981/718 Cayman models originally equipped with PCCB (Porsche Carbon Ceramic Brakes).

Note: Always verify caliper/hat clearance, wheel clearance, and rotor dimensions on the specific vehicle before installation.

Lightweight, high-performance rotor engineering

Each rotor ring is precision-machined from a proprietary high-carbon cast iron. The vanes act as a centrifugal pump to pull cooling air through the hub during repeated hard stops. With a reusable 6061-T6 aluminum hat and replaceable rings (D2-035 / D1-035), these rotors are engineered for longevity and reduced cost over full replacements.
