DBA 2017+ Subaru STi Front Slotted 4000 Series Rotor

When you're looking to get the most out of your 2018-2021 Subaru WRX's braking system, DBA's 4000 Series T3 slotted rotor is a solid choice. This is a single front rotor, designed as a direct replacement for your stock unit, but with significant upgrades to handle more demanding driving conditions. It's built with XG-150 high carbon alloyed iron, a material chosen for its ability to withstand the extra stress and heat that comes with harder braking.

What really sets this rotor apart is DBA's patented Kangaroo Paw ventilation system. Instead of traditional straight vanes, this rotor uses a series of 144 diamond and teardrop-shaped pillars. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard rotors. This means better heat dissipation, which helps prevent brake fade during spirited driving or repeated stops. The T3 slotting pattern is also bi-directional, helping to sweep away gases and dust from the pad surface for more consistent braking performance.

DBA also puts these rotors through a process called Thermal Stability Profiling. This heat treatment helps to stabilize the metal, further improving its resistance to thermal stress and cracking over time. If you're looking for an improved braking component that can handle more heat and provide more reliable stopping power for your WRX, this DBA rotor is a well-built option.
