The GiroDisc 08-16 Audi S4/S5 (B8) Slotted Rear Rotors (A2-130) are purpose-built replacement rotors designed specifically for the B8-chassis Audi S4 and S5, giving track-driven and daily-driven cars alike a durable, high-performance braking upgrade at the rear axle. As a slotted rotor from GiroDisc, a brand built around two-piece rotor construction for motorsport and street use, the A2-130 is engineered to be a direct bolt-on replacement for your factory rear rotors without requiring other brake system modifications.
Key Features & Benefits
- Slotted rotor face helps manage gas and debris at the pad/rotor interface, supporting consistent pedal feel during repeated hard braking.
- GiroDisc two-piece rotor design philosophy — GiroDisc is known in the enthusiast and track community for building rotors around a two-piece, floating hat/ring concept rather than a traditional one-piece casting, which is the foundation of their product line.
- Direct-fit rear rotor for the B8 S4/S5 platform, intended to be a straightforward upgrade over the OE rear rotor for owners chasing better braking performance.
- Purpose-matched to a specific chassis and model range rather than a universal fit, reducing guesswork during fitment selection.
