The DBA 4000 Series T3 rear slotted brake rotor is engineered for high-performance applications, offering superior stopping power and heat dissipation for BMW models including the 328i xDrive, M235i, M240i, 320i xDrive, and 230i. Constructed from XG-150 high carbon alloyed iron, these rotors are designed to withstand intense braking stress and high temperatures generated during spirited driving, track days, or heavy-duty use. The thermal stability profiling (TSP) process ensures consistent performance under thermal stress, making them ideal for vehicles that demand durability and reliable braking performance.
Featuring DBA’s patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars, these rotors deliver up to 30% more surface area and 20% better cooling efficiency compared to traditional straight vane designs. This innovative ventilation reduces brake fade, increases rotor lifespan, and enhances overall braking response. The T3 slotted design incorporates CNC-machined tri-symmetrical slots that increase gas and debris evacuation, resulting in more consistent pad contact, improved responsiveness, and a smoother pedal feel. The universal slot pattern eliminates the need for left or right-specific rotors, simplifying installation and maintenance.
Designed as a direct replacement for OEM rotors, these DBA rotors are suitable for street driving, SUV, light utility vehicles, rally, and track use. They are finished with thermo-graphic paint markings for easy identification and include moisture-proof packaging to prevent corrosion during storage and shipment. The robust construction and advanced ventilation system make these rotors a premium choice for enthusiasts seeking high-performance braking with long-lasting durability and enhanced safety.
