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

A 2-piece rotor design, like this DBA 5000 Series, separates the friction ring from the hat. This allows the cast-iron ring to expand and contract more freely with temperature changes, reducing the risk of warping. The aluminum hat also helps to reduce overall weight and manage heat transfer.

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

The 'XD' designation on DBA rotors refers to their non-directional cross-drilled and dimpled face. This pattern is designed to enhance structural support for the friction ring, improve cooling by allowing gases and heat to escape, and provide a sporty aesthetic.

Can I replace just the rotor ring if it wears out?

Yes, the DBA 5000 Series is a 2-piece rotor system. This means you can purchase replacement friction rings separately and bolt them onto the existing aluminum hat, which can be more cost-effective for future maintenance.

Product Details

When you're pushing your 2015-2021 Nissan GT-R Nismo hard, whether on the street or the track, keeping your braking system in top shape is crucial. These DBA 5000 Series 2-piece rotors are a direct replacement designed to handle the demands of high-performance driving.

DBA builds these rotors with a high-carbon cast-iron friction ring, which is known for its ability to handle heat and resist warping. The standout feature here is the 2-piece construction, using an aerospace-grade T6061-T6 aluminum hat. This aluminum hat not only cuts down on unsprung weight, which can improve handling, but it also helps manage heat by reducing its transfer from the rotor ring to the hub assembly. The XD face features a non-directional drilled and dimpled pattern that helps with cooling and provides a sporty look, while also offering structural support to the friction ring.

These rotors are assembled with National Aerospace Standards (NAS) bolts and crimp nuts, ensuring a solid connection between the hat and the rotor ring. This design allows the cast-iron ring to expand and contract uniformly as it heats and cools. If you ever need to replace just the friction ring down the road, DBA offers replacement rings that can be bolted onto these same hats, making future maintenance more straightforward.
