DBA DBA52472BLKXD 5000 Series XD 2-Piece Cross-Drilled & Dimpled Brake Rotors (Pair)

The DBA DBA52472BLKXD is a fully assembled pair of 5000 Series XD 2-piece front brake rotors featuring a non-directional cross-drilled and dimpled (XD) finish in a black anodized aluminum hat. Measuring 320 x 28mm, these rotors are engineered for 17/18-inch wheel applications.

5000 Series 2-Piece Composite Construction:

• High-carbon cast-iron rings paired with aerospace-grade T6061-T6 aluminum hats, secured with National Aerospace Standards (NAS) bolts and crimp nuts for maximum durability
• Aluminum hat construction reduces unsprung weight while allowing uniform radial disc expansion and minimizing heat transfer from disc to hub
• XD (Cross-Drilled & Dimpled) finish — combines drilled holes and dimples for increased outgassing exit points, improved structural support over traditional full cross-drill designs, and an aggressive sport appearance
• Kangaroo Paw ventilation system — 144 diamond and teardrop-patterned pillars deliver up to 20% improved cooling efficiency versus conventional straight-vane vented rotors, minimizing brake fade and prolonging pad and rotor life
• Universal non-directional design eliminates the need for separate left and right rotors, simplifying fitment and inventory
• Thermographic Heat Paint (TGHP) — paint markings change color at specific temperature thresholds, allowing drivers to monitor peak rotor temperatures and rotor fatigue for informed pad selection decisions
• Thermal Stability Profiling (TSP) — proprietary DBA heat-cycling process applied to high-carbon iron to relieve internal manufacturing stresses, maximizing thermal stability and reducing metal fatigue under sustained heavy braking
• Black EnShield coating on non-friction surfaces reduces corrosion and enhances appearance

Sold as a pair (2 rotors). Recommended for high-performance street vehicles, track days, club racing, and rally applications where maximum heat management and braking consistency are required.
