DBA 08-17 Subaru WRX STI Rear 4000 Series Plain Rotor – High Carbon Alloyed Iron, Thermal Stability Profiling

Description

The DBA 08-17 Subaru WRX STI Rear 4000 Series Plain Rotor is engineered for high-performance braking with durability and efficiency in mind. Crafted from XG-150 high carbon alloyed iron, this rotor undergoes advanced Thermal Stability Profiling (TSP) to ensure consistent performance under intense heat and stress. The use of high-quality materials and proprietary metallurgy allows the rotor to withstand the demanding conditions of aggressive driving and frequent braking cycles, making it a reliable choice for enthusiasts and racers alike.
DBA’s innovative Kangaroo Paw ventilation system features a series of 144 diamond and teardrop patterned pillars that significantly enhance heat dissipation. This design results in up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors. The improved airflow helps reduce brake fade, maintains optimal braking performance, and extends the lifespan of the rotor, ensuring reliable operation during demanding driving conditions.
This rotor features a smooth OE-style finish, providing a clean, factory-like appearance suitable for drivers who seek performance upgrades without compromising the vehicle’s original aesthetic. Its direct replacement design makes installation straightforward, offering compatibility and ease of use for those familiar with OEM parts. The rotor is also protected with moisture-proof corrosion-resistant packaging, ensuring it arrives in optimal condition and maintains longevity even in harsh environments. Whether used in controlled race divisions or daily driving, the DBA 4000 Series HD rotor offers excellent thermal stability, durability, and cooling efficiency, making it a versatile upgrade for your Subaru WRX STI.
