4000 Series T3 Rear Disc Brake Rotor

The DBA DBA42733S is a high-performance, single-piece rear disc brake rotor engineered as a direct replacement for standard OE components. It is part of the 4000 Series T3 line, incorporating DBA's patented T3 bi-directional slot design. This design enhances braking performance by increasing out-gassing exit locations, which improves stop uniformity and efficacy. Constructed from XG150 high carbon alloy iron, this rotor is built to withstand the stresses of demanding driving conditions, reducing the likelihood of warping and cracking and thereby extending its service life. This advanced cooling helps to reduce brake fade, especially during performance driving or towing scenarios. Key specifications for the DBA42733S include an outside diameter of 309mm, a nominal thickness of 10mm, and an overall height of 61.8mm. It is a solid rotor type with 5 lug holes and a slotted surface. The material composition of high carbon alloy iron, combined with its slotted surface and advanced ventilation, contribute to its 5/5 stopping power rating and a 4 out of 5 for performance over stock, suitable for Track Day/Towing applications. This rotor is designed for various Toyota Sienna models from 2011-2020, as well as specific years and trims of Lexus RX350, RX450h, and Toyota Highlander. It is recommended for Performance Street, Street & Track Events, Extreme & Fleet Duty, and Towing-Oversized Tires driving qualifiers.
