Product Description

The **DBA 42339S 4000 Series T3 Rear Brake Rotor** is a performance-oriented direct replacement rotor engineered for a range of Infiniti luxury and sport models. Featuring DBA's advanced T3 tri-symmetrical slot design and patented Kangaroo Paw ventilation system, this rotor improves brake pad bite, enhances outgassing surface area, and increases cooling efficiency for consistent brake performance under street and spirited driving conditions.

Cast from high carbon alloyed iron with a CBN-finished surface and Thermal Stability Profiling (TSP), the DBA 42339S rotor resists common heat-related issues like warping and uneven wear. Painted non-friction areas help resist corrosion while maintaining a clean appearance on the rear hubs of compatible Infiniti vehicles. This rotor is ideal for owners seeking improved rear brake performance without requiring modifications to existing brake systems.
