The high carbon content in the gray cast iron improves thermal stability, while the full coating on both the disc and hat surfaces helps prevent rust and extends rotor life. This product line is engineered to meet the demands of BMW 525i drivers seeking consistent braking performance under various driving conditions.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThe Pagid 355109902 disc brake rotor is constructed from gray cast iron, a material known for its excellent heat absorption and dissipation properties. The rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. Both the disc and hat are coated to resist rust, which is critical for maintaining rotor integrity and performance over time. With a nominal thickness of 24.00 mm and a discard thickness of 22.40 mm, this rotor provides a balance between longevity and safety. The 310 mm outside diameter and 77.10 mm height ensure proper fitment and compatibility with the BMW 525i braking system. The 6 bolt hole configuration matches the vehicle’s hub for secure installation.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 525i\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise caused by rust or uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency by reducing heat-related fade\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor damage with coated surfaces\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Pagid 355109902 rotor on a BMW 525i, ensure the hub surface is clean and free of debris to promote proper rotor seating. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness specification of 22.40 mm. Use the correct torque specifications for the 6 bolt holes to avoid rotor warping. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor lifespan.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003ePagid rotors undergo strict quality control to meet OEM standards for fitment and performance.
