DBA DBA43146XD 4000 Series XD Cross-Drilled & Dimpled Front Brake Rotor

The DBA DBA43146XD is a 4000 Series XD (Cross-Drilled & Dimpled) brake rotor engineered for high-performance street and track driving. Designed specifically for the front axle of the Hyundai i30 N Performance (PDE) Hatch and Fastback 2.0L Turbo (02/2018 onward), this rotor delivers superior thermal management and braking performance over standard OEM discs.

DBA's 4000 Series XD rotors combine cross-drilling and dimpling in a single rotor design. The cross-drilled holes promote rapid gas and heat dissipation, while the precision-machined dimples help sweep away brake dust and debris from the pad surface — maintaining consistent bite and reducing brake fade under hard, repeated braking.

Key Features:

• XD (Cross-Drilled & Dimpled) Technology: Dual surface treatment for maximum cooling and pad sweep efficiency
• 4000 Series Construction: Premium metallurgy with DBA's consistent rotor thickness variation (RTV) control for reduced vibration and noise
• Kangaroo Paw (KP) Venting: DBA's patented Kangaroo Paw ventilation design increases airflow through the rotor by up to 18% compared to standard vented rotors, dramatically reducing rotor temperatures
• Zinc Dichromate Coating: Corrosion-resistant finish on non-swept surfaces to resist rust and maintain appearance
• Street and Track Ready: Engineered to perform under both everyday driving conditions and spirited or track-day use
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Australian Engineered: Designed and quality-controlled by Disc Brakes Australia (DBA), a leading performance brake manufacturer

The DBA43146XD is an ideal upgrade for Hyundai i30 N Performance owners seeking improved braking confidence, reduced brake fade, and enhanced rotor longevity compared to factory equipment.
