Audi S4 Brake Rotor (1) - Rear Right - Stoptech - Sport Cross-Drilled, Black E-Coated - Black - `04-`09. A direct-fit aftermarket rear-right rotor designed for enthusiasts who want improved brake response and corrosion protection while retaining stock calipers.

StopTech Sport Cross-Drilled rotors are one-piece direct replacements that help manage heat, gases and brake dust for a more consistent pedal feel. The cross-drilled pattern assists in dispersing heat and debris to reduce pad glazing and provide sharper initial bite in both wet and dry conditions. The black e-coating offers corrosion resistance and a tidy finish behind wheels. Built with high-carbon metallurgy and double-disk grinding, these rotors aim to deliver a uniform friction surface and reduced tendency toward pad squeal when used with higher-friction European-style pads.
