4000 Series T3 340mm Slotted Vented Brake Rotor

The DBA 4000 Series T3 is a performance aftermarket brake rotor designed to offer superior braking performance beyond standard Original Equipment (OE) levels. Manufactured by Disc Brakes Australia (DBA), this rotor is constructed from high-carbon alloyed iron, which is heat-treated using Thermal Stability Profiling (TSP) to withstand the increased stress and heat generated during intense braking. A key feature of this rotor is DBA's patented Kangaroo Paw ventilation system. The T3 slot profile further enhances braking by providing more exit points for brake pad friction dust and gases, ensuring consistent performance. Key technical specifications for the DBA42722S include an outside diameter of 340 mm, a nominal and discard thickness of 32 mm, and an overall height of 83.5 mm. It is a vented rotor with 5 lug holes and a slotted surface type. The center hole diameter measures 112 mm. This specific rotor (DBA42722S) is compatible with 2008-2010 Lexus LX570 and 2008-2017 Toyota Land Cruiser models. A specific fitment note indicates that for the 2016-2017 Toyota Land Cruiser, it applies to models with a 340mm disc, particularly those manufactured in Mexico.
