DBA 16-19 Audi TT Quattro (w/300mm Rear Disc Excl TTS/RS) Rear 4000 Series Plain Rotor

DBA's 4000 Series disc brake rotors are direct replacement single-piece brake rotors designed for upgraded performance braking. They are cast from XG-150 high carbon alloyed iron and undergo Thermal Stability Profiling (TSP) for increased stress and heat handling. Featuring DBA's patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars, they achieve up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs. The 4000 Series HD variant has a smooth OE style rotor finish, suitable for drivers wanting the benefits of a 4000 Series rotor with an OE look, especially for controlled race divisions. Additional features include thermographic temperature monitoring (heat paint markings change color at specific temperature thresholds to indicate peak braking temperatures) and paint protection on non-friction areas to reduce corrosion and enhance appearance.
