DBA 4000 Series T3 Drilled & Slotted Rear Brake Rotor for Subaru WRX STI 2008-2017 & BRZ w/ Performance Package 2017+
The DBA 4000 Series T3 Drilled & Slotted Rear Brake Rotor is engineered for precision, durability, and high-performance driving. Crafted by Disc Brakes Australia (DBA), a global leader in brake rotor manufacturing with over 40 years of expertise, this rotor is designed to deliver consistent stopping power for both street and track applications. Whether you’re navigating tight corners in your 2008-2017 Subaru WRX STI or pushing your 2017+ Subaru BRZ with Performance Package to its limits, this rotor ensures reliable braking under intense conditions.
Why Choose the DBA?
The DBA 4000 Series T3 rotors are built with advanced technology to enhance braking efficiency. Featuring XG-150 high carbon alloyed iron and Thermal Stability Profiling (TSP), these rotors withstand extreme heat and stress, making them ideal for performance driving, track days, rally, and even heavy-duty applications like 4x4s or armored vehicles. The patented Kangaroo Paw ventilation system, with 144 diamond and teardrop pillars, increases surface area by up to 30% and improves cooling efficiency by 20% compared to traditional straight-vane designs, reducing brake fade during prolonged use. The T3 tri-symmetrical slot design, combined with cross-drilled holes, provides multiple exit points for brake pad friction dust and gases, ensuring a smoother, quieter brake pedal feel and consistent performance with every stop.
The universal slot design eliminates the need for separate left and right rotors, simplifying installation while maintaining precision. Thermo-graphic paint markings (THGP) allow drivers to monitor rotor temperature, ensuring optimal performance during spirited driving. With moisture-proof corrosion protection packaging, these rotors arrive ready for installation, built to last in demanding conditions.
