DBA T3 4000 Series front slotted rotor for 2014–2016 BMW 435i Gran Coupe (F36). Cast from XG-150 high-carbon alloy iron and treated with Thermal Stability Profiling, the rotor uses DBA’s Kangaroo Paw ventilation and bi-directional T3 slots to increase surface area and cooling efficiency compared to straight vane designs. It’s a direct replacement single-piece rotor combining improved heat control with slotted braking surface benefits.
