The DBA Street Series T2 slotted rotor for 2013–2018 BMW 640i front fitment employs CNC-machined bi-symmetrical T2 slots to offer a quieter, more responsive and smoother brake pedal feel while increasing exit points for friction dust and gases to enhance pad bite. DBA’s universal T2 slot design removes left/right rotor orientation and is recommended for more demanding street braking.
