Audi S6 Brake Rotor (1) - Rear - DBA - 4000 Series HD - `13-`19. A direct-replacement rear rotor engineered for drivers who want improved thermal management and OE-style appearance for 2013–2019 Audi S6 models with iron discs.

This DBA 4000 Series HD rotor is cast from XG-150 high carbon alloyed iron and processed with DBA's Thermal Stability Profiling (TSP) to resist cracking and warping under repeated heavy braking. The rotor uses DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars to increase surface area and improve cooling versus traditional straight vane designs. The HD variant keeps a smooth OE-style finish for a factory look while offering better heat dissipation and long-term durability for spirited street driving and controlled track use.

Features

• XG-150 high carbon alloyed iron construction for improved strength and wear resistance
• TSP – Thermal Stability Profiling to reduce the risk of thermal cracking
• Kangaroo Paw ventilation (144 diamond & teardrop pillars) for enhanced cooling
• Smooth OE-style 4000 Series HD finish for a factory appearance
• THGP thermographic paint markings and moisture-proof corrosion protection packaging
• Direct replacement fitment for 2013–2019 Audi S6 rear (vehicles with iron discs)

This rotor is a practical upgrade for enthusiasts who want better brake performance under repeated high-load use without changing the look of the car. The improved surface area and ventilation can deliver up to a 30% increase in surface area and about a 20% improvement in cooling efficiency compared to traditional straight vane designs, helping to maintain braking consistency during sustained use.
