DBA 17-21 BMW 230I (w/M Sport Brakes/348mm Front Rotor) Front 4000 Series Standard Rotor

These DBA 4000 Series HD rotors feature a smooth, OE-style finish, making them a popular choice for drivers who want the performance benefits of the 4000 Series but prefer a factory look. This is especially true for controlled race divisions where appearance matters. The 348mm front rotor is designed to fit a range of vehicles, including the BMW 230i (2017-2021), Mercedes-Benz S450 (2018, 2020), and Mercedes-Benz S560 (2019-2021), among others.

The 4000 Series HD variant is built to handle more demanding driving conditions than a standard rotor. While it maintains the appearance of a stock rotor, it incorporates design elements that help with heat dissipation and consistent braking performance. This makes them a solid option if you're looking for an upgrade that won't drastically change the visual appeal of your wheels.

When replacing your rotors, it's always a good idea to inspect your brake pads and consider replacing them at the same time to ensure optimal braking performance and even wear. Always refer to the manufacturer's installation instructions for specific details.
