Lexus IS300 Brake Rotor (1) - Front - DBA - 4000 Series Plain - `16-`20. A direct-replacement front rotor engineered by Disc Brakes Australia for drivers who want dependable OE-style looks with performance-focused metallurgy.

This DBA 4000 Series HD plain rotor is cast from XG-150 high carbon alloyed iron and undergoes Thermal Stability Profiling (TSP) to reduce the risk of cracking and improve wear characteristics under repeated heavy braking. The rotor uses DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, which increases surface area and improves cooling efficiency versus traditional straight vane designs. The 4000 Series HD 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.
