DBA's 5000 Series two-piece drilled and slotted rotor ring for 2005–2006 Holden VZ with AP Racing 6-piston calipers is a composite direct-replacement rotor that pairs high-carbon cast-iron rings with aerospace-grade T6061-T6 aluminum hats. NAS bolts secure the assembly; the aluminum hats reduce unsprung weight, improve heat management and allow uniform disc expansion. Recommended for high-performance street, track day and rally applications.
