Technical Specifications and Features

This Zimmermann disc brake rotor features a 330 mm outer diameter and a 28 mm brake disc thickness, providing a robust braking surface. 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.

Application and Problem Solving

• Replacement for worn or warped brake rotors on Porsche Cayenne
• Improves braking performance by reducing heat-related fade
• Addresses rotor corrosion and surface degradation
• Restores proper rotor thickness for safe braking
• Ensures compliance with ECE R90 safety standards

Installation Notes and Tips

When 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.
