DBA 43051-10 Subaru WRX STI 4000 Series Stand Rear Brake Rotor with OE Finish

Description

The DBA 43051-10 Subaru WRX STI 4000 Series Stand Rear Brake Rotor is engineered from XG-150 high carbon alloyed iron, undergoing Thermal Stability Profiling to ensure durability under intense braking conditions. This advanced metallurgy allows the rotor to withstand increased stress and heat generated during aggressive driving or racing applications, providing reliable performance over time.
Featuring DBA’s patented Kangaroo Paw ventilation, this rotor incorporates a series of 144 diamond and teardrop patterned pillars to maximize surface area and improve cooling efficiency. Compared to traditional straight vane designs, this innovative pattern offers up to a 30% increase in surface area and a 20% enhancement in cooling performance, helping to prevent overheating and brake fade during demanding scenarios.
The 4000 Series HD variant maintains a smooth OE-style rotor finish, offering an aesthetic that aligns with factory specifications while delivering the benefits of high-performance braking technology. Ideal for drivers in controlled race divisions or those seeking a clean, OEM appearance combined with enhanced thermal stability and braking performance. This rotor also features thermo-graphic paint markings for easy temperature monitoring, direct replacement compatibility, and moisture-proof packaging to ensure corrosion resistance. Its design is suitable for replacement on Subaru WRX STI models, providing a reliable upgrade that meets OEM standards without requiring additional modifications. Overall, the DBA 43051-10 rotor combines innovative engineering, high-quality materials, and precision manufacturing to deliver consistent, high-performance braking for spirited driving and racing applications.
