The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the specific braking demands of performance-oriented vehicles like the BMW X5, offering a balance between durability and effective heat management.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 10.4 mm, ensuring it meets safety standards for replacement intervals. The 324 mm outside diameter and 80.1 mm overall height are tailored to fit the BMW X5 brake assembly precisely. The rotor features a directional surface pattern with drilled holes and slots that help evacuate gases and debris, improving braking consistency. The zinc silver finish on the hat section provides rust resistance, which is critical for maintaining structural integrity over time. The rotor includes five bolt holes with a diameter of 16.6 mm arranged on a 120 mm bolt circle diameter, matching the BMW X5's hub specifications.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW X5 models\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eAddresses corrosion issues with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eEnhances braking performance in wet conditions through slotted and drilled design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 10.4 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the BMW X5 hub using the 120 mm bolt circle diameter and 16.6 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction to maintain optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for fit and function on BMW X5 vehicles.
