Product Description

The DBA DBA43058S 4000 Series T3 Slotted Front Brake Rotor is a direct replacement performance rotor engineered for select Subaru vehicles. Its advanced Tri-symmetrical slot pattern works together with Kangaroo Paw ventilation to help evacuate heat, friction gases, and debris more efficiently than standard rotors under repeated braking cycles. Constructed from high carbon alloyed iron and enhanced with Thermal Stability Profiling (TSP), this rotor resists heat-induced distortion and improves durability compared with conventional OEM rotors.

Ideal for spirited street driving, daily commuting, and moderate performance use, the DBA43058S delivers improved pad bite, heat management, and braking feel. Designed to fit the front braking systems of 2009-2018 Subaru Forester AWD models with 2.5L engines and extend into newer AWD Subaru WRX applications (2022-2025), it installs easily into factory mounting locations. Sold individually, this rotor is perfect for performance-focused Subaru owners looking to upgrade braking efficiency and responsiveness.
