Product Description

The DBA 4000 Series XS Drilled & Slotted Front Brake Rotor with dual bolt pattern (DBA4654XS-10) is a high-performance direct replacement rotor engineered for select Subaru and Toyota/Scion vehicles that use a 10-lug front mounting configuration. Its drilled holes and slots work together to optimize heat dissipation, increase brake pad bite, and evacuate dust, gas, and water from the friction surface for more consistent performance under spirited driving and heavy usage conditions. The Kangaroo Paw internal ventilation design further enhances airflow for improved cooling compared to conventional rotors.

Built from high carbon alloyed iron and enhanced with Thermal Stability Profiling (TSP), the rotor resists heat-induced warping and cracking while maintaining structural strength. The universal bi-directional design means this rotor can be installed on either front side without orientation concerns. Thermo-graphic paint indicators give visual feedback on surface heat ranges during operation. Sold individually, this rotor lets you replace one side at a time or order two for a complete front axle upgrade to elevate braking performance and confidence on compatible WRX STI, BRZ, and Toyota 86 front brake systems.
