This front disc brake rotor drops in as a direct-fit replacement across the listed applications — including the 2018-2024 BMW X3, 2019-2024 BMW 330I and 330I XDRIVE, 2021-2024 BMW 430I and 430I XDRIVE, 2019-2025 BMW X4, 2019-2024 BMW Z4, 2022-2025 BMW 230I, 2021-2024 BMW 330E, and more (engine: All) — see the Buyer's Guide tab for the full list.
- OE-Style Design: engineered to match OE requirements and help restore like-new braking performance.
- Resists Corrosion: painted edges and hats provide reliable corrosion resistance.
- Precision Finish: the precision-ground surface finish requires less pad break-in time and aids proper bedding for consistent performance, noise reduction and heat dissipation.
- Smooth Braking & Balance: application-specific OE vane design and thickness help control noise, vibration and harshness (NVH), while precision machining limits vibrations for improved stability, control and reduced pad wear.
Built from high-grade metallurgy with full-cast, vented construction and a smooth surface, this rotor measures 12.990 in (330.0 mm) outside diameter. Sold individually; the listed applications use two per axle, so replace both sides together as a matched pair for even, balanced braking. Country of origin: China.
