DBA 12-15 Lotus Exige Front 5000 Series Slotted Ring

The DBA 5000 Series HD replacement rotors are engineered as a two-piece direct replacement for 2012–2015 Lotus Elise/Exige applications. They deliver the proven materials and construction of the 5000 Series with a smooth OE-style finish. The DBA 5000 Series HD combines high-carbon cast-iron rings with aerospace-grade aluminum hats (T6061-T6), secured with National Aerospace Standards (NAS) bolts and crimp nuts. The two-piece design reduces unsprung weight, helps manage heat more effectively by isolating disc and hub temperatures, and allows uniform radial disc expansion under load. The HD variant provides the 5000 Series performance technology without slots, dimples, or cross-drilling, making it a good choice for drivers who want improved thermal control and durability while retaining an OEM-style surface.
