Girodisc D1-130 Audi B8 S4/S5 Front Ring FAQs
Can I use these rings with the OEM Audi rotor hats? No. These rings are only compatible with Girodisc aluminum hats and cannot mount to factory one-piece or ceramic setups.
Which pad compounds are recommended? For street and light track use, Ferodo DS2500 are ideal. For aggressive track applications, use Pagid RS29 for consistent high-temperature performance.
Are these rotors directional? Yes. Each rotor is clearly marked for left or right installation, ensuring the curved vanes channel air correctly through the disc for optimal cooling.
What torque specification should I use on the hardware? Tighten all hardware bolts to 12 ft-lbs (16 Nm) using blue Loctite, and recheck torque after one full heat cycle or track session.
