What is the benefit of a 2-piece rotor design?

A 2-piece rotor design, like this one, uses a separate aluminum hat and cast iron rotor ring. This construction helps reduce unsprung weight, which can improve vehicle handling. It also allows for better heat management, as the aluminum hat helps dissipate heat and allows the iron ring to expand more uniformly under braking.

What does the T3 slotting do on these rotors?

The T3 slotting on these DBA rotors is a patented design that helps sweep away brake dust and gases from between the brake pad and the rotor surface. This action helps maintain consistent braking performance, especially during demanding use like track days or spirited driving.

Can I replace just the rotor ring later on?

Yes, the 5000 Series rotors are designed so you can replace the cast iron rotor rings (flat discs) in the future while reusing the aluminum hats. This can be a cost-effective option for long-term use on high-performance vehicles.

About this part

Product Details

DBA is known for making serious brake components, and their 5000 Series rotors are a prime example of that. If you're looking to upgrade the rear braking performance on your 2015, 2017, or 2018 Ford Mustang, especially if you're pushing it on the street or track, these 2-piece rotors are a solid choice.

These aren't just standard rotors; they're a composite design. The braking surface is made from high-carbon cast iron, which is a well-built material for handling heat. This iron ring is bolted to a T6061-T6 aerospace-grade aluminum hat. This two-piece construction does a couple of important things. First, the aluminum hat significantly cuts down on unsprung weight compared to a solid one-piece rotor, which can help with overall vehicle dynamics. Second, the aluminum hat helps manage heat transfer away from the hub and allows the cast iron braking ring to expand evenly as it heats up, reducing the risk of warping. DBA also uses their patented T3 slot design on the braking surface. These slots help sweep away dust and gas that can build up between the pad and rotor, keeping your braking consistent, especially during hard stops.

This package includes the complete assembly, meaning the hat and the rotor ring are already bolted together and ready for installation. DBA recommends these for high-performance street use, track days, and club racing. If you plan on replacing just the rotor rings in the future, you can reuse these aluminum hats, which is a nice touch for long-term ownership.
