DBA 15-20 Audi S3 Front 5000 Series Drilled & Slotted Ring

What you get here is a single DBA 5000 Series XD front brake rotor ring. This is the cast iron friction surface that bolts to the aluminum hat, sold separately or as part of a complete assembly. It's designed as a direct replacement for vehicles like the Audi S3, Volkswagen GTI, and Volkswagen Arteon, offering a significant upgrade for high-performance street driving, track days, and club racing.

DBA builds these 5000 Series rotors with a high-carbon cast-iron ring that's cross-drilled and dimpled. This XD finish isn't just for looks; it helps dissipate heat and gas more effectively than standard finishes, which means more consistent braking performance when things get hot. The two-piece design, when paired with an aerospace-grade aluminum hat, also helps reduce unsprung weight and allows the cast iron ring to expand and contract evenly with temperature changes, further improving performance and longevity. These are built to handle serious use, combining advanced materials with a focus on heat management and weight reduction.

If you're looking to get the most out of your braking system, especially if you plan on hitting the track or pushing your car hard on the street, this rotor ring is a solid choice. Remember that this is just the rotor ring itself; you'll need the corresponding aluminum hat and NAS bolts to complete the assembly. DBA offers these as replacement parts so you can reuse your existing 5000 Series hats if you're just replacing worn-out rings.
