DBA 4000 Series T3 Slot Brake Rotor

The Stillen DBA 4000 Series T3 Slot Brake Rotor is engineered by Disc Brakes Australia (DBA) for drivers seeking performance braking beyond standard OE levels. This direct replacement rotor is cast from high carbon alloyed iron and subjected to Thermal Stability Profiling (TSP). This process allows the metallurgy to withstand the elevated stress and heat generated during intense braking applications. This particular rotor utilizes DBA's patented Kangaroo Paw ventilation system, which comprises 144 diamond and teardrop-shaped pillars. This design contributes to a significant increase in surface area, resulting in up to a 30% improvement in cooling efficiency compared to traditional straight vane designs, ensuring consistent performance under demanding conditions. Key technical specifications for this front rotor include an outside diameter of 338 mm, a nominal and discard thickness of 32 mm, and a center hole diameter of 108 mm. It is a vented rotor with a slotted surface type and features 6 lug holes. The DBA 4000 Series T3 Slot Brake Rotor is compatible with 2010-2023 Lexus GX460 and 2010-2022 Toyota 4Runner models.
