What is a two-piece rotor system and how does this part fit in?

A two-piece rotor system separates the rotor ring from the rotor hat (or bell). This allows for easier replacement of just the worn rotor ring, which is what the DBA52120.1S is designed for. You can reuse your existing rotor hats with these replacement rings.

What is the benefit of the T3 slot design?

The T3 slot design is uni-directional and bi-directional, which helps to keep the rotor surface clean by sweeping away brake dust and gases. This leads to more consistent braking performance, especially under heavy use.

Does this rotor ring come with the rotor hat or hardware?

The DBA52120.1S is a replacement rotor ring only. It is designed to be used with your existing two-piece rotor hats and associated hardware. Please refer to your original two-piece rotor kit for any specific installation requirements.

About this part

Product Details

DBA is well-known for making performance brake components, and their 5000 Series T3 brake rings are a prime example of that expertise. These are designed as direct replacement rotor rings for popular two-piece rotor systems, meaning you can keep your existing bells and just swap out the worn-out rotor surface. This particular ring is the DBA52120.1S, featuring DBA's patented T3 slot design.

The T3 slotting is unique because it's uni-directional and bi-directional, helping to sweep away dust and gas that can build up between the pad and rotor. This means you get a more consistent grip, especially during hard braking. The rotor ring itself is built to handle the demands of performance driving, offering a solid option for drivers looking to refresh their braking system without replacing the entire two-piece assembly. This rotor ring fits a range of vehicles, including models like the 2007-2013 Mazda 3, 2013-2018 Ford Focus ST (with 320mm front rotors), and 2015-2018 Lincoln MKC.
