DBA's 4000 Series front slotted rotors for 2012–2020 BMW 1 and 3 Series (F20/F30) use the patented T2 slot design. CNC machined bi‑symmetrical slots increase exit points for dust and gases, improving pad bite while delivering a quieter, more responsive and smoother brake pedal feel. The universal slot removes the need for left/right specific rotors, making these direct replacements for more intensive braking applications.
