The DBA 5000 Series replacement ring is a two-piece composite rotor ring pairing high-carbon cast-iron rings with aerospace-grade aluminum hats (T6061-T6) to reduce unsprung weight and improve heat control. Assembled with NAS bolts and crimp nuts, DBA offers assemblies or replacement rings so hats can be reused. This ring fits the front of 2012–2013 Volkswagen Golf R and is suitable for spirited street and track driving.
