Acura ILX Brake Rotor (1) - Rear - DBA - 4000 Series HD - `16-`22. This genuine DBA 4000 Series HD rear rotor is a direct-fit replacement designed for drivers who want improved thermal management and reliable, OE-style performance for 2016–2022 ILX models.

Cast from XG-150 high carbon alloyed iron and treated with Thermal Stability Profiling (TSP), this rotor resists heat fade and maintains structural integrity under repeated heavy braking. The 4000 Series HD version retains a smooth, OEM-style finish while incorporating DBA’s patented Kangaroo Paw ventilation — a pattern of 144 diamond and teardrop pillars that increases surface area and enhances cooling compared to straight-vane designs. The rotor also features THGP thermo-graphic paint markings for heat monitoring, is packaged with moisture-proof corrosion protection, and is intended as a direct replacement for the factory rear rotor.

Features

• XG-150 high carbon alloyed iron construction for strength and wear resistance
• Thermal Stability Profiling (TSP) to reduce the risk of thermal cracking
• Patented Kangaroo Paw ventilation (144 pillars) for up to 30% more surface area and improved cooling
• Smooth OE-style 4000 Series HD finish with THGP thermo-graphic paint markings
• Moisture-proof corrosion protection packaging and direct replacement fit
