What is a 2-piece rotor and why would I need a replacement ring?

A 2-piece rotor separates the braking surface (the ring) from the hub assembly (the hat). This design allows for better heat management and reduced weight. You'd need a replacement ring if your current DBA 5000 Series rotor ring is worn out, but your aluminum hat is still in good condition.

Does this replacement ring come with the aluminum hat?

No, this product is specifically the replacement rotor ring only. It is designed to be used with an existing DBA 5000 Series aluminum hat. The hat and NAS bolts are sold separately or as part of a complete assembly.

What is the benefit of the aluminum hat on this rotor?

The aerospace-grade aluminum hat helps to reduce the unsprung weight of the brake assembly, which can improve vehicle handling. It also helps to manage heat by reducing its transfer from the cast iron rotor ring to the wheel hub.

About this part

Product Details

If you're working on a 2015, 2017, or 2018 Ford Mustang equipped with the GT Performance Package, this DBA 5000 Series replacement rotor ring is for the rear brakes. It's a two-piece rotor designed to offer improved performance, especially when you're pushing your Mustang hard, whether on the street, track days, or club racing.

This rotor ring is made from high-carbon cast iron and pairs with an aerospace-grade aluminum hat, held together with NAS bolts. The aluminum hat helps reduce unsprung weight and manage heat better than a traditional one-piece rotor. This specific part is just the rotor ring itself, allowing you to reuse your existing DBA 5000 Series aluminum hat if you're replacing worn rings. The smooth, OE-style finish is a popular choice for those who want the performance benefits without the look of drilled or slotted rotors.
