The DBA 4000 Series T3 rear rotor for Lexus IS F (2007–2009) is a direct-replacement performance rotor cast from XG-150 high carbon alloyed iron and processed with Thermal Stability Profiling. It uses DBA’s Kangaroo Paw ventilation—144 diamond and teardrop pillars—to boost surface area and cooling efficiency. The T3 bi-directional slot design combines the 4000 Series metallurgy benefits with slotted faces for improved pad bite and heat management under repeated heavy braking.
