The DBA 5000 Series two-piece slotted rotor with black hat is a front direct-replacement for 2004–2006 Audi TT Quattro 3.2L applications, pairing high-carbon cast-iron rings with aerospace-grade T6061‑T6 aluminum hats fastened with NAS bolts. This composite design reduces unsprung weight, improves heat management and allows uniform disc expansion. DBA recommends the 5000 Series for high-performance street use, track days and club racing.
