The DBA 4000 Series T3 Slotted Brake Rotor is engineered for high-performance driving and heavy-duty applications. Cast from XG-150 high carbon alloyed iron, this rotor offers exceptional durability and thermal stability, ensuring reliable performance under intense braking conditions. The unique Kangaroo Paw ventilation system, featuring 144 diamond and teardrop patterned pillars, provides up to a 30% increase in surface area and a 20% boost in cooling efficiency over traditional straight vane designs, helping to prevent brake fade during prolonged or aggressive stops. The rotor’s thermographic paint markings allow for thermal profiling during operation, making it ideal for street, off-road, and track use. Built as a direct replacement for OEM components, the rotor is designed to fit 2018-2021 Subaru WRX models, ensuring quick and hassle-free installation. The patented T3 bi-directional slot pattern enhances heat dissipation and brake pad cleaning, resulting in quieter, smoother pedal feel and improved responsiveness. The CNC-machined tri-symmetrical slots increase exit points for gases and dust, maintaining consistent braking performance across multiple stops. Suitable for performance street driving, rally, light utility, and armored vehicles, the DBA 4000 Series T3 rotors combine advanced metallurgy with innovative design to deliver dependable, high-performance braking. Each rotor is moisture-proof and packaged with corrosion protection for long-lasting reliability. Whether on the street or the track, this rotor offers a premium upgrade to your vehicle’s braking system, ensuring safety and performance are never compromised.
