Bring smoother, more confident stops to your sedan with the DYNAMIC FRICTION brake rotor 604-73032, a direct-fit rear replacement for the 2004-2009 Audi S4. This DFC GEOSPEC coated blank rotor is CNC-machined to tight tolerances and arrives ready to install with no additional pre-degreasing preparation needed.
Designed to meet the same form, fit, and function as OEM brake rotors, it drops in as a direct-fit rear replacement for the listed Audi S4 applications. Warped or worn rotors can cause pedal pulsation, vibration under braking, or reduced stopping feel; if the rotor is the cause, replacing it restores a proper braking surface. Sold individually — replace both rear rotors together as a matched pair for even, balanced braking.

Are these Audi S4 rotors for the front or rear?

What is the DFC GEOSPEC coating?
It is a corrosion-protective coating DFC states provides superior protection over zinc or conventional painting, and the rotor ships ready to install with no pre-degreasing needed.
What material is this rotor made of?
It is cast from premium G3000/G11H18 iron and CNC-machined to tight tolerances, then 100% precision cut and mill-balanced for smoother stops.
Do I need to replace both S4 rotors at once?
Rotors are sold individually. Replacing both rear rotors together as a matched pair is recommended for even, balanced braking, though not strictly required.
