The fully coated surfaces help prevent rust buildup, extending the rotor's service life, while the high carbon content in the gray cast iron improves thermal stability and wear resistance. This combination supports consistent braking performance for BMW vehicles like the 330Ci, 330i, 330xi, and Z4.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThe Pagid disc brake rotor 355121992 is constructed from gray cast iron, a material known for its excellent heat dissipation and mechanical strength. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. The rotor’s nominal thickness of 25.00 mm ensures a solid braking surface, while the discard thickness of 23.40 mm indicates when replacement is necessary to maintain safety. Both the disc and hat are coated to resist rust and corrosion, which is critical for maintaining rotor integrity over time. The full cast construction provides a robust and reliable component that meets the demands of BMW braking systems. With six bolt holes and a 325 mm outside diameter, this rotor is engineered for precise fitment on compatible BMW models.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 330Ci, 330i, 330xi, and Z4\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise and vibration issues caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency by reducing heat-related fade\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion that can compromise rotor performance\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor discard thickness is checked before installation\u003c\/li\u003e\n\u003cli\u003eClean mounting surface to prevent uneven rotor seating\u003c\/li\u003e\n\u003cli\u003eTorque bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary during rotor installation\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\u003ePagid rotors are manufactured to meet OEM standards for fit, form, and function.
