Product Description

The **DBA 42663S-10 4000 Series T3 Rear Brake Rotor** is a high-performance direct replacement rotor engineered for select rear brake applications on Subaru and Toyota sports cars and crossovers. Featuring DBA's advanced T3 tri-symmetrical slot pattern and patented Kangaroo Paw ventilation system, this rotor enhances brake pad bite while efficiently evacuating heat, dust, and gases generated under braking - delivering consistent stopping performance and smoother pedal feel during street, spirited, and occasional track use.

Constructed from premium XG-150 high carbon alloyed iron and treated with Thermal Stability Profiling (TSP) to reduce stress and warping under repeated heavy braking cycles, the DBA 42663S-10 offers strong thermal resilience and durability compared with standard OEM rotors. Its uni-directional slot design allows installation on either rear side without left/right distinction, while dual bolt pattern compatibility (5x100 mm and 5x114.3 mm) provides versatile fitment across various compatible vehicles. Sold individually, this rotor is ideal for drivers seeking a performance upgrade over stock rear rotors for Subaru BRZ, Scion FR-S, Toyota 86/GR86, and compatible Legacy and Crosstrek models.
