DBA two-piece front brake disc for Infiniti Q40, Infiniti Q50

Introducing DBA 5000 Series XS Brake Rotors, engineered with a distinctive cross-drilled and slotted design to maximize brake performance. This innovative design increases the number of exit points, allowing brake pad friction dust and gases to escape efficiently through both the cross-drilled holes and slots, resulting in superior braking performance. These rotors embody DBA’s commitment to cutting-edge technology, featuring two-piece direct replacement construction with CBN machine-turned finishes and high carbon alloy composition.

Enhancing performance further, DBA’s Kangaroo Paw ventilation system delivers a remarkable 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. But the benefits don’t stop there. These rotors are available in a range of color finishes on the rotor hub and the rotor rings come equipped with Thermographic heat paint markings. These markings transition in color at specific temperature thresholds, providing a visual cue for monitoring braking temperatures and assessing rotor fatigue, ensuring precision performance.

The incorporation of aerospace-grade aluminum hats isn’t just for looks; it reduces unsprung weight and facilitates uniform radial disc expansion within the cast iron rings. Additionally, it acts as a heat barrier, preventing heat transfer from the disc to the hub through the aluminum hats.

DBA’s dedication to performance is evident in the meticulous use of top-tier materials. High carbon cast iron rings are seamlessly integrated with Aluma-lite center hats/bells, securely fastened together using National Aerospace Standards (NAS) bolts and crimp nuts. Choose from complete assemblies for initial replacements or opt for replacement hats and replacement rotors, providing flexibility and cost-effectiveness.

While offering similar performance benefits to the T3 slot, the XS is a popular choice for show cars, combining performance with additional aesthetic appeal.
