4000 Series T3 Single-Piece Brake Rotor

The DBA 4000 Series T3 rear rotor is engineered as a direct-fit, single-piece upgrade for drivers seeking performance beyond standard OE levels. This rotor features DBAs patented world-renowned T3 bi-directional slot design, which incorporates precise CNC-machined tri-symmetrical slots. This design enhances braking responsiveness and smoothness by increasing the exit points for friction dust and gases, leading to more consistent brake stops. The T3 slotting is specifically recommended for high-performance driving and heavy off-roading scenarios. Constructed from high carbon alloyed iron and subjected to Thermal Stability Profiling, these rotors are built to withstand the increased stress and heat generated during intense braking applications. The metallurgy ensures repeated reliability. Furthermore, they incorporate DBA's Kangaroo Paw ventilation system, which utilizes a series of diamond and teardrop patterned pillars. This unique vane design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs, significantly boosting braking effectiveness and extending brake life. Key features include anti-rust painted non-friction areas for enhanced appearance and rust prevention, and bi-directional symmetry for universal left/right use. The rotors also benefit from Thermal Stability Profiling for increased rotor stability and durability, as well as center-split core castings for improved heat transfer. A Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation, reducing pad knock and premature wear. Thermographic heat paint markings help monitor braking temperatures and rotor fatigue. This rotor has a 326mm outer diameter and is designed for rear axle fitment.
