Girodisc Porsche 350mm Rear Rotors

Upgrade the braking performance of your Porsche 997 Turbo with Girodisc’s lightweight 350mm rear rotors. Designed for both PCCB and non-PCCB vehicles, these direct-fit rotors reduce unsprung mass, improve cooling efficiency, and provide consistent braking power on road or track.
Vehicle Fitment
Porsche 997 Turbo (All Models)
Works with PCCB and non-PCCB brake systems
Direct OEM replacement – bolts to factory calipers and hardware
Built for Precision and Performance
The Girodisc system replaces the OEM rotor with a two-piece floating assembly that combines a CNC-machined 6061-T6 aluminum hat and a proprietary cast-iron friction ring, both produced in the USA. The curved vane internal design functions as a centrifugal pump, drawing air through the rotor to keep temperatures stable under heavy braking. This setup maintains factory brake bias and ABS calibration while delivering quicker cooling and improved pedal feel.

Girodisc A2-032 Rear Rotor FAQs:
Will these work on both PCCB and steel-rotor cars? Yes. They’re engineered to fit either configuration of the 997 Turbo without modification, using your factory calipers and hardware.
How do they compare to the factory PCCB rotors? Girodisc rotors offer improved heat tolerance and lower long-term costs, with performance closer to a motorsport-grade iron system while retaining OEM compatibility.
What benefits will I notice on track? Expect better heat management, reduced fade, and more consistent pedal feel—even during repeated high-speed braking sessions.
Are they serviceable? Absolutely. When the friction rings wear out, they can be replaced separately, making these rotors a long-term performance investment.
