DBA T3 Slotted Rear Brake Rotor

The DBA DBA4789S is a high-performance rear brake rotor engineered to exceed standard OE levels. It is part of DBA's 4000 Series T3 line, incorporating advanced technology and materials for maximum stopping power and durability. The rotors are cast from XG150 High Carbon Alloy Iron, a material treated to handle the increased stress and heat generated during intense braking. This ventilation system, combined with Tri-symmetrical curve slots, helps to reduce brake fade, noise, and vibration, leading to a quieter and smoother pedal feel while improving stopping uniformity. The T3 slot design is universal, eliminating the need for left or right specific rotors, and increases the number of out-gassing locations for brake pad friction gasses. These rotors are recommended for a variety of demanding applications, including extreme & fleet duty, towing with oversized tires, performance street driving, and track events. Each rotor is sold individually. Specific technical details include an outside diameter of 330 mm, a nominal thickness of 18 mm, and 5 lug holes. The rotor material is high carbon alloy iron, and the surface type is slotted. The temperature monitoring feature on the rotor helps drivers track peak braking temperatures.
