DBA DBA52774SLVXD 5000 Series XD Cross-Drilled & Dimpled 2-Piece Brake Rotor - Front

The DBA DBA52774SLVXD is a front 5000 Series XD two-piece composite brake rotor featuring a non-directional cross-drilled and dimpled surface finish. Engineered for high-performance street driving and show vehicles, the XD design delivers enhanced cooling benefits and an aggressive sports aesthetic over standard smooth-face rotors.

Two-Piece Composite Construction:

• High carbon cast iron rotor ring (XG-150 alloy) with Thermal Stability Profiling (TSP) — a proprietary heat-cycling process that relieves internal stresses and maximizes thermal stability
• Aerospace-grade T6061-T6 aluminium hat reduces unsprung weight and limits heat transfer from the disc to the hub and wheel bearings
• Assembled with National Aerospace Standards (NAS) bolts and crimp nuts — torque to 13 Nm / 9.6 ft-lb
• Rotor diameter: 380mm | Axle position: Front

XD Surface Finish:

• Non-directional cross-drilled holes combined with dimples for improved cooling and gas/dust evacuation
• Dimples provide enhanced structural support compared to fully drilled designs, reducing the risk of stress fractures
• Delivers cooling performance above the HD (smooth) finish with added visual appeal
• Not recommended for track or motorsport use — intended for street performance and show applications

DBA Performance Technologies Included:

• Kangaroo Paw vane design — 144 diamond and teardrop-shaped pillars in the ventilation path for up to 20% better heat dissipation versus conventional vented rotors
• Thermo-Graphic Heat Paint (TGHP) — 9 paint markings that change color at specific temperature thresholds to monitor braking heat and rotor fatigue
• Uniform radial disc expansion design prevents warping under sustained heavy braking

Replacement Flexibility: The 5000 Series two-piece design allows for replacement of the cast iron ring independently of the aluminium hat, making ongoing maintenance more cost-effective for performance drivers. Sold as a single rotor; two are required per axle.
