Product Description

The **DBA 42656XS-10 4000 Series XS Drilled & Slotted Rear Brake Rotor** is a high-performance direct replacement rotor engineered for the **Subaru WRX STI** rear braking system across 2008 through 2017 model years. Featuring a cross-drilled and slotted surface along with DBA's patented Kangaroo Paw ventilation design, this rotor increases brake pad bite and accelerates heat and gas evacuation for more consistent braking performance under spirited and street driving conditions.

Constructed from premium **XG-150 high carbon alloyed iron** and treated with Thermal Stability Profiling (TSP) to reduce stress and warping when exposed to repeated heavy braking, the DBA 42656XS-10 offers excellent thermal resilience and durability compared with standard OEM rotors. Its gold painted hat adds corrosion resistance and visual flair, and the universal uni-directional design allows the rotor to be installed on either rear side without orientation concerns. Ideal for performance-oriented drivers seeking both functional improvements and enhanced aesthetics for their WRX STI.
