The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service 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 heat management.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional surface pattern with drilled holes and slots helps evacuate gases, dust, and water, improving brake pad contact and reducing fade. The rotor's nominal thickness is 30 mm, with a discard thickness of 28.4 mm, ensuring safe replacement intervals. The rotor features five bolt holes with a diameter of 16.6 mm and a bolt circle diameter of 120 mm, matching the BMW X5's hub specifications. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped BMW X5 brake rotors\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eEnhances braking performance in wet or dusty conditions with slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains proper fitment and alignment with precise bolt hole and center hole dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (28.4 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean hub surface to prevent rotor runout and ensure proper fit\u003c\/li\u003e\n\u003cli\u003eTorque bolts to manufacturer specifications for BMW X5\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary when installing new rotors\u003c\/li\u003e\n\u003cli\u003ePerform a bed-in procedure after installation to optimize braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31135L rotor to meet OEM standards for fit and function on BMW X5 vehicles.
