Audi TT Quattro RS Brake Rotor (1) - Front - DBA - 5000 Series HD - 2012-2013. This genuine DBA 5000 Series HD front rotor ring is a direct replacement designed for owners of the TT Quattro RS with the 370mm front rotor, offering a durable, performance-oriented upgrade for street and occasional track use.

The 5000 Series HD is a composite two-piece design that shares the core technologies of DBA’s 4000 Series while adding weight savings and improved thermal management through an aerospace-grade aluminum hat (T6061-T6). High carbon cast-iron rings provide consistent friction characteristics, while National Aerospace Standards (NAS) bolts and crimp nuts secure the assembly. The HD variant features a smooth, OE-style rotor finish for drivers who prefer a clean face without slots, cross-drilling, or dimpling. This ring is intended as a replacement disc ring and can be combined with DBA hats or replacement rings as needed.

Features

• Composite 2-piece construction: high carbon cast-iron ring + T6061-T6 aluminum hat
• NAS bolts and crimp nuts for aerospace-level retention
• Reduced unsprung weight and improved heat isolation from hub
• Smooth OE-style finish—no slots or drilling
• Direct replacement fit for 2012–2013 Audi TT Quattro RS (370mm front)
