A1-355 Girodisc Audi 8Y RS3 Front Iron Conversion

These Girodisc A1-355 2-piece front iron rotors are a direct bolt-on conversion for the Audi 8Y RS3. They replace the factory carbon ceramic or one-piece iron rotors with a lightweight, high-performance 2-piece design that reduces unsprung weight and improves thermal performance for both street and track use.

Vehicle Fitment

• Audi RS3 8Y (Front)

Lightweight, Serviceable Two-Piece Design

The Girodisc A1-355 system uses high-carbon iron rotor rings mated to aluminum hats for improved heat management and cost-effective service. The 48 curved vane design pulls air through the rotor for excellent cooling under repeated heavy braking, making it ideal for track days and performance driving. When the rings wear out, they can be replaced separately without buying a full rotor assembly again.
