The rotor’s vented design helps maintain optimal operating temperatures by allowing air to flow between the rotor surfaces, reducing the risk of brake fade. The directional surface pattern is engineered to optimize braking efficiency and pad contact.\u003c\/p\u003e\u003cp\u003eThe rotor’s nominal thickness is 28 mm, with a discard thickness of 26.4 mm, ensuring a long service life before replacement is necessary. The zinc black hat finish provides corrosion resistance, complemented by an overall rust-resistant coating to protect the rotor from environmental damage. The rotor features five bolt holes with a diameter of 16.65 mm and a bolt circle diameter of 120 mm, matching the BMW X3 and X4 specifications precisely.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on BMW X3 and X4\u003c\/li\u003e\n\u003cli\u003eImproves braking performance under wet or high-heat conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during aggressive driving or towing\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion on braking surfaces\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness and braking efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern and diameter match your vehicle’s hub assembly. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
