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

The 2-piece design, with its aluminum hat and cast-iron ring, significantly reduces unsprung weight compared to a traditional one-piece rotor. It also offers improved heat management, allowing the friction ring to expand uniformly and reducing heat transfer to the hub.

What does the 'XD' finish mean on this rotor?

The XD finish features a non-directional pattern of drilled holes and dimples. This design helps with cooling by allowing gases and heat to escape more efficiently, and it also provides an enhanced sporty appearance.

Can I replace just the rotor ring or the hat if needed?

Yes, DBA offers replacement hats and flat disc rotors (rings) for the 5000 Series. This means you can reuse your existing DBA 5000 Series hats if you need to replace the friction rings in the future.

About this part

Product Details

DBA has built a solid reputation for creating high-performance brake components, and their 5000 Series rotors are a prime example of that expertise. If you're looking to significantly upgrade your braking system, especially for spirited driving, track days, or club racing, this 2-piece rotor is designed to meet those demands. It's a direct replacement for a range of vehicles, including models like the Infiniti Q50 and Nissan Murano, offering a substantial improvement over stock components.

What sets the 5000 Series apart is its composite construction. It combines a high-carbon cast-iron friction ring with an aerospace-grade T6061-T6 aluminum hat. This isn't just for looks; the aluminum hat significantly reduces unsprung weight, which can improve overall vehicle handling. It also helps manage heat, allowing the cast-iron ring to expand uniformly and reducing heat transfer to the hub. The XD finish features a non-directional drilled and dimpled pattern that not only looks sporty but also aids in cooling and clearing gases and dust more effectively than standard finishes.

This rotor is sold as a complete assembly, meaning the hat and the friction ring are already bolted together with NAS bolts, ready for installation. DBA also offers replacement hats and rings separately, so if you ever need to refresh your setup, you can reuse the existing DBA 5000 Series hats. This makes it a well-considered investment for drivers who push their vehicles hard and demand consistent, reliable stopping power.
