The UV coating enhances the rotor's resistance to rust, making it suitable for drivers seeking longevity and consistent braking performance without compromising OE standards.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThe Brembo 09.B338.21 rotor is constructed from high carbon steel, providing a balance of hardness and thermal conductivity. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. The rotor measures 300mm in outside diameter and 66mm in height, with a centering diameter of 75mm to ensure precise alignment on the hub. The nominal thickness is 20mm, with a minimum thickness threshold of 18.40mm to maintain safe braking performance. The rotor includes five mounting holes and comes with fixing screws for ease of installation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for BMW 325xi models requiring a 300mm vented disc\u003c\/li\u003e\n\u003cli\u003eSuitable for BMW 328i and 328i xDrive vehicles needing high carbon rotors\u003c\/li\u003e\n\u003cli\u003eFits BMW 328xi and X1 models with matching rotor specifications\u003c\/li\u003e\n\u003cli\u003eAddresses issues such as rotor warping, excessive brake noise, and uneven pad wear\u003c\/li\u003e\n\u003cli\u003eIdeal for restoring braking efficiency and reducing rust-related rotor degradation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Brembo 09.B338.21 rotor, ensure the hub surface is clean and free of debris to maintain proper centering. Use the included fixing screws to secure the rotor firmly. It is recommended to inspect brake pads and hardware during installation and replace if necessary to optimize braking performance.
