The rotor is internally vented, allowing air to flow through the disc to reduce heat buildup during braking. With a bolt hole circle diameter of 130 mm and 5 holes arranged in an 8\/5 pattern, it fits securely on the Porsche Cayenne hub. The centering diameter measures 98 mm, ensuring precise alignment. The rotor height is 73.5 mm, and it weighs approximately 8.4 kg. The high-carbon machining process enhances the rotor's resistance to wear and thermal stress, while the coated surface offers protection against corrosion and environmental factors. The minimum thickness specification is 26 mm, which is critical for maintaining braking efficiency and safety.\u003c\/p\u003e\u003ch2\u003eApplication and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped brake rotors on Porsche Cayenne\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by reducing heat-related fade\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion and surface degradation\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor thickness for safe braking\u003c\/li\u003e\n\u003cli\u003eEnsures compliance with ECE R90 safety standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Zimmermann disc brake rotor 460.4523.20, ensure the rotor surface and hub are clean and free of debris to maintain proper fitment. Verify the bolt hole circle and centering diameter match the vehicle specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness regularly to avoid operating below the minimum thickness of 26 mm. Proper torque specifications should be followed when securing the rotor to prevent warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Compliance\u003c\/h2\u003e\u003cp\u003eThe Zimmermann disc brake rotor 460.4523.20 carries an ECE R90 approved inspection tag, confirming it meets European safety and quality standards for replacement brake components.
