DBA 00-06 Audi TT/TT Quattro Front 4000 Series Plain Rotor

A single front replacement rotor engineered for drivers who want the durability and thermal control of DBA's 4000 Series HD in an OE-style plain finish. This rotor is cast from XG-150 high carbon alloyed iron and undergoes DBA's Thermal Stability Profiling (TSP) to resist the elevated stress and heat of repeated heavy braking. The patented Kangaroo Paw ventilation uses 144 diamond and teardrop patterned pillars to increase surface area and improve cooling versus traditional straight vane designs. The 4000 Series HD variant provides the performance benefits of the 4000 line while retaining a smooth OEM-style appearance, making it suitable for street-driven cars and controlled race divisions where a plain rotor is preferred. It ships in moisture-proof corrosion protection packaging and includes THGP thermographic paint markings for quality verification.
