Porsche 997.1 Carrera / Carrera S
Includes caliper spacers and bolts for installation
Direct replacement – compatible with factory calipers and hardware
Engineered for Porsche Precision
The Girodisc system replaces the factory rotor with a larger, two-piece floating design engineered for performance and longevity. Each assembly pairs a CNC-machined 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction rings, both made in the USA. The curved internal vane structure acts as a centrifugal pump, forcing air through the rotor for enhanced cooling. With its increased rotor size and floating design, this upgrade delivers superior heat management and more consistent braking under repeated high-speed stops.

Girodisc A2-033 Rear Rotor FAQs:
Why is this rotor larger than stock? The Girodisc system increases diameter to 325mm, providing greater mechanical leverage and improved heat capacity for stronger, more consistent braking.
Do I need to modify my calipers to fit these? No. The kit includes custom spacers and bolts that perfectly reposition the calipers for the larger rotors—no cutting or permanent changes required.
Will these affect brake bias or ABS? Not at all. Girodisc engineers each system to maintain the factory balance and ABS performance while increasing cooling efficiency.
Are they suitable for track or aggressive driving? Absolutely. The curved vane design and floating assembly deliver exceptional fade resistance and durability, making them ideal for spirited street or track use.
Upgrade your Porsche’s stopping power with Girodisc rear rotors—engineered to bring race-level precision and confidence to your 996 or 997.1 Carrera.
