4000 Series T3 Slotted Brake Rotor

The DBA DBA42184S 4000 Series T3 brake rotor is engineered for drivers seeking enhanced braking performance beyond standard OE levels. This direct-replacement, single-piece rotor is constructed from XG150 High Carbon Alloy Iron, designed to resist warping and cracking for extended rotor life. Its advanced metallurgy, enhanced by Thermal Stability Profiling (TSP), allows it to withstand the increased stress and heat generated during intense braking applications. The rotor's unique T3 bi-directional slot design offers multiple benefits, including decreasing vibration and noise for a quieter, smoother brake pedal. The increased number of out-gassing exit locations for brake pad friction gasses contributes to improved brake stop uniformity and efficacy. Additionally, the universal slot design eliminates the need for left and right specific discs, simplifying installation and inventory. This feature, combined with the high-carbon iron construction, reduces brake fade and improves overall braking performance, making it suitable for extreme and fleet duty, towing, oversized tires, performance street driving, and track events. Key specifications include an outside diameter of 320mm, a vented rotor type, and a 5-stud/lug hole quantity. The rotor is coated for rust protection on non-friction areas and is sold individually. It is specifically designed for the front of various Infiniti and Nissan models, including the 2015-2022 INFINITI Q50, 2019-2020 INFINITI Q60, 2016-2017 INFINITI QX50, 2019 INFINITI QX60, 2017-2018 Nissan Murano, and 2014-2019 Nissan Pathfinder.
