The DBA 4000 Series High Performance Brake Rotor is engineered with advanced metallurgy, cast from XG-150 high carbon alloyed iron, ensuring durability and heat resistance under demanding braking conditions. Undergoing rigorous Thermal Stability Profiling, this rotor maintains optimal performance during intense braking, making it ideal for high-performance and street applications. Its patented Kangaroo Paw ventilation features 144 diamond and teardrop-shaped pillars, increasing surface area by up to 30% and enhancing cooling efficiency by 20% compared to traditional straight vane designs, which helps prevent fade and prolong rotor life.
The 4000 Series HD variant offers a smooth OE-style rotor finish, providing a clean, factory appearance while delivering the benefits of high-performance braking. Designed for drivers in controlled race divisions or those seeking a OEM-style look, this rotor offers a perfect blend of form and function. The inclusion of Thermo-graphic paint markings allows for quick temperature assessments, while moisture-proof packaging ensures corrosion resistance for long-lasting performance.
This direct replacement rotor is suitable for a range of Audi models, including the 2008-2011 Audi S4 and S5, offering hassle-free installation and reliable stopping power. Whether used for daily driving, spirited street use, or competitive racing, the DBA 4000 Series rotor provides consistent, high-quality braking performance that meets demanding automotive standards.
