Product Description

The GiroDisc A1-032A 2-piece slotted front brake rotors are engineered to provide superior performance over stock components. Designed as direct replacements for the factory 330mm rotors on select Porsche models, these rotors feature a lightweight aluminum hat and a slotted cast iron disc, reducing unsprung weight and enhancing thermal management.

With a diameter of 350mm and a thickness of 34mm (outer) / 32mm (inner), these rotors maintain the OEM brake bias and ABS functionality, ensuring seamless integration with the factory braking system. The curved vane design acts as a centrifugal pump, directing cool air across the rotor surface to improve cooling efficiency during high-performance driving.

Ideal for both street and track applications, the GiroDisc A1-032A rotors offer a significant upgrade over stock components, providing improved braking performance, reduced weight, and enhanced durability.
