The DBA 4000 Series T3 Slotted Brake Rotor is a high-performance, direct replacement rotor designed for Mazda MX-5 Miata models from 2017 to 2018 and Fiat 124 Spider from 2018. Crafted from XG-150 high carbon alloyed iron, this rotor offers exceptional thermal stability and durability under intense braking conditions. Its innovative Kangaroo Paw ventilation system features 144 diamond and teardrop-patterned pillars, which significantly improve heat dissipation and surface area, resulting in up to a 30% increase in cooling efficiency compared to traditional straight vane designs. This advanced ventilation technology ensures consistent braking performance during spirited driving, track days, or heavy-duty use. The 4000 Series T3 rotor incorporates DBA’s patented T3 bi-directional slot design, which enhances brake pad debris and gas evacuation, providing a quieter, more responsive, and smoother pedal feel. The CNC-machined tri-symmetrical slots are precisely engineered to increase exit points for gases and dust, maintaining consistent brake performance and reducing fade during repeated stops. Built on the proven foundation of the T2 slot design, the T3 slots are universal and eliminate the need for left or right-specific rotors, simplifying installation and ensuring optimal performance on both sides. Featuring Thermo-graphic paint markings for easy thermal profiling and moisture-proof packaging for corrosion resistance, this rotor is built to meet the demands of street, performance, and light utility vehicle applications. Whether for daily driving, rally, or light track use, the DBA 4000 Series T3 Slotted Rotor provides reliable, high-quality braking performance, making it an ideal choice for enthusiasts seeking enhanced stopping power and rotor longevity.
