The DBA 4000 Series rotor is a direct-replacement front rotor for 2008–2014 Lexus IS F applications. Cast from XG-150 high-carbon alloyed iron and produced with Thermal Stability Profiling, it features Kangaroo Paw ventilation that increases surface area and cooling efficiency versus straight-vane designs. The 4000 Series HD variant also offers a smooth OE-style finish for drivers seeking factory appearance with improved thermal performance.
