DBA 2015+ Subaru Liberty 2.5L 4000 T3 Slotted Street Series Rear Rotor

The T3 slotting pattern on this DBA 4000 series rear rotor is a key design choice that helps keep your brakes performing their best. These slots aren't just for looks; they help sweep away gas and dust that can build up between the pad and rotor surface, which means you get a more consistent grip, especially when you're braking hard. This makes them a solid option for your 2018-2021 Subaru WRX, whether you're driving daily or pushing it a bit harder.

DBA builds these rotors with their Thermo-Spec™ treatment, a thermal bake process that helps strengthen the iron and reduce the chance of warping or cracking, even under heavy use. The T3 slots are machine-cut for precision, and the rotor itself is made from a high-carbon cast iron that's well-built to handle the demands of braking. This combination means you're getting a rotor that's designed to last and perform reliably, giving you more confidence behind the wheel.

When you're replacing your rear rotors, it's always a good idea to inspect your brake pads and consider replacing them at the same time if they're worn. This ensures you get the full benefit of your new rotors and maintain balanced braking performance across your WRX.
