DBA 16-20 Lexus IS300 RWD Front 4000 Series Plain Rotor

Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this DBA 4000 Series HD plain rotor is engineered for durability and to reduce the risk of cracking and improve wear characteristics under repeated heavy braking. It features DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, which increases surface area by up to 30% and improves cooling efficiency by up to 20% compared to traditional straight vane designs. The rotor offers a smooth OE-style finish while retaining performance benefits, and includes thermo-graphic paint markings (THGP) and moisture-proof corrosion protection packaging for reliable service life and fitment.
