Audi S4 Brake Rotor (1) - Rear - DBA - 4000 Series Plain - `10-`19 is a direct-replacement rear rotor designed for 2010–2019 Audi S4 models. This DBA 4000 Series HD plain rotor delivers a smooth OE-style surface finish while using DBA’s proven metallurgy and cooling design for consistent braking under demanding conditions.

Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor is built to withstand repeated high-stress braking. DBA’s patented Kangaroo Paw ventilation uses 144 diamond and teardrop-patterned pillars to increase surface area and improve cooling efficiency versus traditional straight vane rotors. The 4000 Series HD variant retains an OE-style smooth face popular with drivers who want performance benefits without a drilled or slotted appearance. Additional features include THGP thermographic paint markings for inspection, direct-fit replacement construction, and moisture-proof corrosion protection packaging for storage and shipping.
