Product Description

The GiroDisc A2-033 slotted 2-piece rear brake rotors are engineered to enhance the braking performance of your 2005-2008 Porsche 911 Carrera 4 (997.1). With a larger 325mm diameter compared to the OEM 298mm, these rotors provide increased braking force and improved cooling capacity. The curved vane design acts as a centrifugal pump, directing airflow through the rotor to reduce brake fade during high-performance driving.

Constructed with U.S.-sourced 6061-T6 aircraft-grade aluminum hats and proprietary cast iron rotor rings, these rotors are both lightweight and durable. The floating two-piece design maintains the factory brake bias and ABS functionality, ensuring seamless integration with your vehicle's existing braking system. Installation is straightforward, with no modifications required, and the kit includes all necessary components.

Ideal for both daily driving and track use, the GiroDisc A2-033 rotors offer a significant upgrade over the stock components, delivering enhanced performance and reliability.
