The DBA 4000 Series T3 Slotted Rotor is a high-performance brake component designed for BMW 3 Series models from 2000 to 2003. Crafted from XG-150 high carbon alloyed iron, this rotor delivers exceptional durability and heat resistance under intense braking conditions. The advanced thermal stability profiling ensures consistent performance during prolonged use, making it ideal for street, track days, and spirited driving. Featuring DBA’s patented Kangaroo Paw ventilation, the rotor benefits from 144 diamond and teardrop patterned pillars that significantly increase surface area and improve cooling efficiency by up to 20% over traditional vane designs.
The T3 design incorporates CNC-machined tri-symmetrical slots that enhance brake responsiveness, reduce dust and gas build-up, and promote quieter operation. These slots are bi-directional, eliminating the need for separate left and right designs, which simplifies installation and ensures optimal pad contact. The rotor’s surface is finished with thermo-graphic paint markings for easy heat assessment and moisture-proof packaging for corrosion resistance. Suitable for a variety of driving applications, including performance street use, SUVs, light utility vehicles, rally, and armored vehicles, the DBA 4000 Series T3 Rotor offers reliable, consistent braking performance.
Installation is straightforward as a direct replacement for factory rotors, and it is engineered to provide superior stopping power, better heat dissipation, and longevity. Whether you’re upgrading your daily driver or preparing for track days, this rotor ensures your braking system is equipped with premium materials and innovative design features for maximum safety and performance.
