High-performance DBA 4000 Series slotted front rotors engineered for superior heat dissipation, reduced brake fade, and enhanced stopping power—compatible with 2018–2021 Subaru STI and 2024+ WRX TR/RS models equipped with Brembo braking systems.

Description

This is the DBA 4000 Series T-Slotted Rotor. This particular rotor features DBA’s T3 Slot 48 precision CNC machined slots that are tri-symmetrical curve slots that help reduce vibration and improve braking performance for the street or the track. This rotor makes for an excellent upgrade when compared to the OEM rotor, and offers better stopping performance from the daily commute to work, or on the next weekend track day. Note that these are sold individually.
