Engineered for Mid-Engine Performance
The Girodisc system replaces the factory cast rotor with a fully rebuildable two-piece floating design. Each rotor features a CNC-machined 6061-T6 aluminum hat and Girodisc’s proprietary cast-iron friction ring, both made in the USA. The internal curved vane layout acts as a centrifugal air pump, maintaining even cooling and consistent friction under extended use. The result is enhanced control and reduced fade for street or track driving.

Girodisc A2-031 Rear Rotor FAQs:
Are these rotors a direct fit for my Boxster or Cayman? Yes. They’re designed to bolt directly onto 986 and 987 chassis cars using the original calipers and hardware—no adapters required.
How do they improve braking over stock? Girodisc rotors are lighter and better cooled, resulting in faster response, improved heat control, and greater fade resistance during hard driving.
Are these rotors suitable for track use? Definitely. The floating design and proprietary iron composition deliver consistent performance even under repeated high-load braking conditions.
Can I use my existing brake pads? Yes. They’re fully compatible with OEM or aftermarket pad compounds, giving you flexibility for street or performance setups.
