DBA 11-16 BMW 328i (F30/F31) / 2013+ BMW 428i/435i (F32/F33/F36) Front Slotted 4000 Series Rotor

If you're looking to get more out of your BMW's braking system, consider these DBA 4000 Series T3 slotted rotors. They're designed as a direct replacement for a range of BMW models, including the 2011-2016 3 Series (like the 328i) and 2013+ 4 Series (like the 428i and 435i). These rotors are built to handle the extra heat and stress that comes with harder driving, offering a solid option for improved stopping power.

DBA casts these rotors from XG-150 high-carbon alloy iron, a well-built material that can stand up to increased braking demands. They also feature DBA's patented Kangaroo Paw ventilation system. This design uses 144 diamond and teardrop-shaped pillars, which DBA says increases surface area by up to 30% and improves cooling efficiency by 20% over standard straight vane designs. The T3 bi-directional slot pattern is also a key feature, helping to sweep away gases and dust for more consistent braking performance, especially during repeated hard stops.

These rotors are a great choice if you're looking for an upgrade over stock without going to a full big brake kit. They fit right onto your existing setup, making the installation straightforward for a mechanic. You'll notice a difference in how your brakes feel, particularly when they're working hard.
