DBA DBA43146S 4000 T3 Slotted Front Rotors for 2018-20 Hyundai i30 N Performance

Vehicle Fitment

• 2018-2020 Hyundai i30 N Performance (PDe, Pre-Facelift, Hatchback, 2.0L Turbo I4 G4KH 202kW, FWD)
• 2018-2020 Hyundai i30 N Performance (PDe, Pre-Facelift, Fastback, 2.0L Turbo I4 G4KH 202kW, FWD)

Fitment Notes

• Front rotor position only. Does not replace rear rotors.
• Sold individually. Order 2 for a complete front axle set.
• Fits Pre-Facelift i30 N Performance (PDe, 2018-2020) models equipped with the 345mm front rotor only.
• Does NOT fit the Facelift i30 N (PDEN, 2021+) which uses a larger 360mm front rotor. Verify your rotor diameter before ordering.
• Fits both the Hatchback (5-door) and Fastback body styles of the Pre-Facelift i30 N Performance.
• Does not fit the standard i30 N (non-Performance) - confirm your trim has the 345mm rotor specification.

Features

• T3 tri-symmetrical bi-directional slot design with 48 precision CNC-machined slots for superior gas and friction dust evacuation under hard braking
• Built on the 4000 Series platform with Thermal Stability Profiling (TSP) for maximum heat resistance and rotor longevity on the i30 N's performance-oriented FWD platform
• Patented Kangaroo Paw ventilation - 144 diamond and teardrop pillars provide up to 30% more surface area and 20% better cooling than straight-vane designs
• XG-150 high-carbon alloyed iron construction minimises warping, cracking, and thermal fatigue under repeated aggressive stops
• CBN (Cubic Boron Nitride) machine-turned friction surface for precise disc thickness variation (DTV) control and consistent pedal feel
• Thermographic Heat Paint (TGHP) markings change colour at specific temperature thresholds for real-time brake temperature monitoring
• Universal bi-directional slot pattern - no separate left/right rotor required
• Anti-rust paint on non-friction areas protects rotor appearance and resists corrosion throughout service life

Product Description

The DBA DBA43146S is a 4000 Series T3 Slotted front brake rotor engineered as a direct OE replacement for the Pre-Facelift Hyundai i30 N Performance (PDe, 2018-2020) in both Hatchback and Fastback body styles. Designed around the factory 345mm front rotor specification, this rotor brings DBA's 4000 Series XG-150 high-carbon iron construction and Thermal Stability Profiling to handle the front-heavy braking demands of the i30 N's performance FWD platform - whether on aggressive street driving, canyon runs, or circuit sessions.

The T3 tri-symmetrical slot design delivers more out-gassing exit points than the T2, keeping pad contamination low and braking response consistent across repeated heavy stops. Pair with DBA Street Performance or Xtreme Performance pads for best results. Note: this rotor is specific to Pre-Facelift PDe models with 345mm front rotors - it is not compatible with 2021+ Facelift i30 N models using the larger 360mm rotor.
