Girodisc Porsche Cayman Iron Conversion Rear Rotors

Convert your PCCB-equipped Porsche Cayman or Boxster to a high-performance iron rotor system with Girodisc’s precision-engineered rear rotors. Designed as a direct replacement for OEM carbon-ceramic discs, these rotors deliver superior heat management, consistent pedal feel, and lower replacement costs without compromising braking balance or ABS function.
Vehicle Fitment
Porsche 987 Cayman S / Cayman R (PCCB-equipped)
Porsche 987 Boxster S (PCCB-equipped)
Direct replacement for factory carbon-ceramic rotors
Bolts directly to OEM calipers—no modifications required
High-Performance Design for Real-World Driving
The Girodisc system replaces the stock PCCB units with a two-piece floating iron rotor designed for durability and serviceability. Each rotor assembly features a CNC-machined 6061-T6 aluminum hat mated to Girodisc’s proprietary cast-iron friction ring. The curved vane internal design functions as a centrifugal air pump, maintaining consistent cooling under high braking loads. This setup preserves factory brake bias and pedal response while offering a more robust and affordable long-term solution for track or street use.

Girodisc A2-049 Rear Rotor FAQs:
Will these work with OEM PCCB calipers? Yes. These rotors are specifically designed for Caymans and Boxsters originally equipped with PCCB systems and bolt directly to the factory calipers.
Why convert from PCCB to iron? Iron rotors offer greater thermal capacity and reduced replacement cost while still providing strong, consistent performance on street or track.
Do these affect brake bias or ABS? No. Girodisc designs each conversion to maintain factory braking balance and ABS function.
Are they rebuildable? Yes. When worn, only the iron friction rings need to be replaced—saving cost and maintaining long-term reliability.
