This coating helps protect the rotor surface from rust and environmental damage, maintaining braking efficiency over time. The high-carbon alloy construction contributes to enhanced thermal stability and wear resistance, making it suitable for BMW models requiring reliable disc brake rotors.\u003c\/p\u003e\u003ch2\u003eProduct Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is designed as a vented type, which allows air to flow between the rotor surfaces, improving heat dissipation during braking. The rotor’s 348 mm outside diameter and 75 mm inside diameter ensure compatibility with the brake system of BMW 535d, 535i, 640i, and related xDrive and Gran Coupe variants. The five bolt holes, each 16.6 mm in diameter, provide a secure fitment to the wheel hub. With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor meets wear specifications to maintain safe braking performance.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 535d and 640i models\u003c\/li\u003e\n\u003cli\u003eImproves heat management to reduce brake fade during extended use\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with GEOMET coating\u003c\/li\u003e\n\u003cli\u003eRestores braking precision and pedal feel in vented rotor applications\u003c\/li\u003e\n\u003cli\u003eCompatible with both standard and xDrive versions of specified BMW models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness is within the discard limits to maintain safety standards. Use proper torque specifications for the five bolt holes to secure the rotor firmly.
