This design improves heat dissipation and reduces brake fade while providing rust resistance. The directional surface pattern enhances water and debris evacuation, making it suitable for BMW 528i and 528i xDrive vehicles requiring reliable braking under varied conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor measures 330 mm in outside diameter and 66.2 mm in overall height, ensuring compatibility with the specified BMW models. The rotor is vented to allow airflow between the rotor faces, which helps maintain optimal operating temperatures during braking. The zinc black hat finish and rust-resistant coating protect against corrosion, extending the rotor's service life. The rotor features five bolt holes with a 16.6 mm diameter and a 120 mm bolt circle diameter, matching the BMW 528i and 528i xDrive hub specifications.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 528i and 528i xDrive\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eSlotted and drilled design helps evacuate water and debris for consistent braking\u003c\/li\u003e\n\u003cli\u003eRust resistant coating prevents corrosion in humid or wet environments\u003c\/li\u003e\n\u003cli\u003eDirectional surface pattern enhances braking performance and pad bite\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 120 mm bolt circle pattern. Check rotor thickness before installation; replace if below the discard thickness of 22.4 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction rotors are manufactured to meet OEM standards for fit and function.
