The Girodisc A2-126 is engineered as a direct replacement for the OE disc on Porsche 997.2 GT3, GT3 RS, and GT2 models produced between 2010 and 2011, as well as the 2007-2009 GT2 and GT3. This rotor is designed to integrate seamlessly with factory calipers, requiring no modifications and allowing the use of unmodified factory pads. This ensures that the original brake bias and ABS functionality are maintained, making it an ideal choice for those looking to enhance braking performance without the complexities of a big brake kit.
The central hat of the Girodisc rotor is crafted from high-grade U.S. sourced 6061-T6 aluminum, known for its lightweight and strength. The rotor itself is manufactured from Girodisc's proprietary cast iron, poured and machined in-house in the USA. This ensures consistent quality and performance.
The rotor features a sophisticated curved vane design, originally developed for racing applications. This design acts as a centrifugal pump, effectively directing cooling air through the rotor to enhance heat dissipation during high-performance driving conditions.
The A2-126 utilizes a floating mount system that incorporates 8 or 10 high-strength alloy steel drive pins, specifically manufactured to Girodisc's standards and cadmium plated for superior corrosion resistance. These pins are designed to handle the loads generated during braking while allowing for axial and radial movement between the rotor and hat. This design minimizes noise and enhances performance by allowing the rotor to self-center between the brake pads.
Installation of the Girodisc A2-126 is straightforward, bolting directly to the vehicle without the need for modifications. When it comes time to replace the rotor, simply swap out the cast iron rotor, maintaining the integrity of the system.
Each set is sold in pairs, ensuring you have everything needed for a complete upgrade.
