DBA DBA43148XD 4000 Series Cross-Drilled & Dimpled Front Brake Rotor

The DBA DBA43148XD is a 4000 Series XD (Cross-Drilled & Dimpled) performance brake rotor engineered for the Hyundai i30 N-Performance (PDE, 2020 and newer). Designed and manufactured in Australia by Disc Brakes Australia (DBA), this rotor delivers superior thermal management and braking performance over standard OEM replacements.

DBA's XD (Cross-Drilled & Dimpled) technology combines through-drilled holes with surface dimples to maximize heat dissipation, reduce brake fade, and efficiently evacuate gases and debris from the rotor surface. The result is consistently strong, fade-resistant braking performance under both everyday driving and spirited or track-day conditions.

Key Features:

• 4000 Series XD Design – Cross-drilled and dimpled surface for maximum cooling and outgassing
• Superior Heat Dissipation – Reduces brake fade during high-performance and repeated braking events
• Kangaroo Paw (KP) Venting – DBA's patented vane technology increases airflow through the rotor by up to 20% compared to standard vane designs
• Geomet® Protective Coating – Corrosion-resistant coating on the non-swept rotor surfaces for long-term durability and clean appearance
• Precision Machined – OEM-quality fit and finish for straightforward, no-modification installation
• Street & Track Ready – Ideal for performance driving and daily use
• Manufactured in Australia – DBA's strict quality control and ISO-certified manufacturing

The DBA43148XD is a direct-fit front replacement rotor, providing a confident upgrade path for i30 N-Performance owners seeking improved stopping power and thermal durability over the stock brake setup.
