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

A two-piece rotor uses separate friction rings and hats. This design allows for reduced unsprung weight by using lighter materials like aluminum for the hat, and it helps manage heat more effectively, leading to more consistent braking performance.

Can I replace just the rotor ring if I already have DBA 5000 Series hats?

Yes, this product is a replacement rotor ring designed to be used with existing DBA 5000 Series hats. This allows you to service your brake system by replacing only the worn friction ring.

What is the T3 slot design for?

The T3 slot design is patented by DBA and is bi-directional. These slots help to sweep away brake dust and gases that can build up between the pad and rotor surface, which helps maintain consistent braking performance and bite.

About this part

Product Details

Starting with T6061-T6 aerospace grade aluminum hats, these DBA 5000 Series rotors are built for performance. They combine a high-carbon cast-iron friction ring with these aluminum hats, held together by NAS bolts and crimp nuts. This two-piece design is a direct replacement for your vehicle's stock rotors, and it's designed to handle demanding driving conditions, whether on the street, track, or rally course.

The aluminum hats offer a couple of key advantages. They significantly reduce unsprung weight compared to a solid one-piece rotor, which can help with overall vehicle dynamics. Plus, the aluminum helps manage heat, allowing the cast-iron ring to expand uniformly and reducing heat transfer to the hub. This means more consistent braking performance, especially during hard stops. DBA's patented T3 slot design on the cast-iron ring also helps clear out dust and gas, further improving braking consistency.

This rotor ring is intended to be used with existing DBA 5000 Series hats, allowing you to replace just the friction ring when it wears out. This setup is popular for high-performance street vehicles and track day applications where braking performance is critical.
