Product Description

The GiroDisc D2-154 slotted rear rotor rings are engineered to provide superior braking performance for a wide range of Porsche models equipped with Porsche Carbon Ceramic Brakes (PCCB). These rotor rings are a direct replacement for the OEM rear rotors and are designed to work seamlessly with the vehicle's existing calipers and GiroDisc aluminum hats.

Constructed from high-carbon cast iron and cryogenically treated, the D2-154 rotor rings offer enhanced durability and resistance to thermal stress, ensuring consistent braking performance under demanding conditions. The slotted design helps to dissipate heat and gases, reducing brake fade and improving overall braking efficiency.

The two-piece construction reduces unsprung weight, contributing to improved handling and responsiveness. The curved vane design promotes better airflow through the rotor, enhancing cooling and extending the lifespan of the braking components.

Whether you're upgrading your braking system for daily driving or performance applications, the GiroDisc D2-154 slotted rear rotor rings deliver the reliability and performance you demand.
