Designed to shed heat and damp noise at the rear axle, the HELLA BRAKES Brake Rotor 355123152 is an internally vented, full-cast rotor made of gray cast iron with high carbon content. It fits many vehicles, among them the 2017-2020 BMW 430i, 2017-2020 BMW 430i Gran Coupe and 2017-2020 BMW 430i xDrive, and it installs as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
- Heat management: High carbon content supports improved heat dissipation, working with the internally vented design.
- Rust protection: A full zinc coating guards against rust, with coated disc and hat finishes.
- Noise and vibration control: High carbon content and 'soft' casting materials are designed to absorb sound and resist deformation.
- Easier installation: The non-oiled surface means no degreasing is needed before you fit this disc brake rotor.
