The DBA Street Series rear slotted rotor for 2016–2019 Audi TT Quattro (with 300mm rear rotor; excludes TTS/RS) uses DBA's patented T2 slot design to improve pad bite and allow friction dust and gases to escape. The CNC-machined bi-symmetrical slots reduce noise and deliver a smoother, more responsive brake pedal feel, recommended by DBA for more intensive braking applications.
