DBA 4000 Series Drilled Front Brake Rotor - 2017 BMW 230I (With M Sport Brakes/348mm Front Rotor)

The DBA 4000 Series Drilled Front Brake Rotor provides a replacement braking surface for 2017 BMW 230I (With M Sport Brakes/348mm Front Rotor).

DBA’s 4000 Series uses high-carbon alloyed iron and Thermal Stability Profiling. This combination is intended to support rotor stability through the repeated heating and cooling associated with demanding braking.

The friction surface and pad compound should be selected together. A rotor upgrade should complement the vehicle’s brake configuration and intended duty rather than substitute for appropriate pads, fluid or cooling.

The friction face combines drilled holes and dimples; select this surface according to the intended application and DBA’s product guidance.
