DBA 5000 Series Slotted Rings High-performance composite 2-piece brake rotors designed for spirited street driving, track days and competitive motorsports. The DBA 5000 Series builds on the proven 4000 platform with aerospace-grade materials and weight-saving design for improved braking consistency and heat management. Premium construction: high-carbon cast-iron rings combined with T6061-T6 aerospace-grade aluminum hats. Advanced fastening: assembled with National Aerospace Standards (NAS) bolts and crimp nuts for reliable, serviceable joints. Performance benefits: slotted ring design for superior pad bite, gas and debris evacuation, and consistent friction under heavy use. Weight & heat management: aluminum hats reduce unsprung mass and limit heat transfer to the hub while permitting uniform radial expansion of the cast-iron rings.
