DBA DBAKIT50003 5000 Series Brake Upgrade Kit

The DBA DBAKIT50003 is a complete brake upgrade kit from Disc Brakes Australia (DBA), built around the renowned 5000 Series platform. Engineered for high-performance street driving, track days, club racing, and rally applications, this kit delivers a significant step up in braking performance over standard OEM components.

5000 Series Technology:

• Two-Piece Composite Rotor Design: Lightweight aerospace-grade aluminum 6061-T6 hats paired with high-carbon cast iron rings, assembled with National Aerospace Standards (NAS) bolts and crimp nuts for maximum strength and reliability
• T3 Bi-Directional Slot Pattern: Precision CNC-machined tri-symmetrical slots increase exit points for brake pad gases and friction dust, delivering quieter, more responsive, and smoother braking
• Kangaroo Paw Ventilation: DBA's patented ventilation system featuring 144 teardrop-shaped pillars provides up to 20% greater cooling efficiency compared to conventional straight-vane rotor designs
• Thermal Stability Profiling (TSP): A proprietary DBA heat-cycling process applied to XG-150 high-carbon iron that relieves internal manufacturing stresses, maximizing thermal stability and reducing metal fatigue under extreme braking loads
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint markings on the rotor edge change color at specific temperature thresholds, providing a visual indicator of peak rotor temperatures and potential rotor fatigue
• Reduced Unsprung Weight: Aluminum hats significantly lower unsprung rotational mass, improving acceleration, deceleration, and overall handling dynamics
• Uniform Radial Disc Expansion: The two-piece design allows the cast iron ring to expand radially during heat cycles without stressing the hub, prolonging rotor life

The DBA 5000 Series is recommended for high-performance street vehicles, weekend track days, club racing, and rally use. DBA (Disc Brakes Australia) has been engineering premium brake components for over 40 years and is trusted as original equipment on numerous performance vehicles worldwide.
