Is this a complete brake rotor assembly?

No, this is a replacement rotor ring only. It is designed to be bolted to a compatible DBA 5000 Series aluminum hat. You will need to reuse your existing hat or purchase one separately.

What is the benefit of the two-piece design with an aluminum hat?

The two-piece design with an aluminum hat helps reduce unsprung weight, which can improve handling. The aluminum hat also helps manage heat by allowing the iron ring to expand evenly and reducing heat transfer to the hub.

What is the difference between the 5000 Series HD and other 5000 Series variants?

The 5000 Series HD variant features a smooth, OE-style rotor finish. Other variants may include slots or cross-drilling for different performance characteristics and aesthetics.

About this part

Product Details

Starting with a T6061 aerospace-grade aluminum hat is a smart move for reducing unsprung weight and managing heat. This DBA 5000 Series rotor ring is designed as a direct replacement for your Infiniti or Nissan, offering a composite two-piece construction that’s built for demanding use. It’s a popular choice for high-performance street driving, track days, and club racing applications where consistent braking is key.

The high carbon cast-iron ring works with the aluminum hat to allow for even expansion of the iron as it heats up, while the aluminum itself helps to keep heat from transferring directly to the hub. This setup is especially beneficial when you’re pushing your vehicle hard, like during spirited driving on winding roads or on the track. The 5000 Series HD variant offers a smooth OE-style finish, which is ideal if you want the performance benefits without the look of slots or cross-drilled holes.

This is a replacement ring only, meaning you can reuse your existing DBA 5000 Series aluminum hats if you're upgrading or replacing worn rings. This approach saves you money and allows you to maintain the performance advantages of the two-piece design. It fits a wide range of Infiniti and Nissan models, including the 370Z, G37, and Q50.
