This combination enhances corrosion resistance while maintaining structural integrity and heat management. The vented design and directional surface optimize braking efficiency and rotor longevity, making it suitable for performance-oriented vehicles like the BMW 228i xDrive Gran Coupe and Mini Cooper series.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design to improve airflow and heat dissipation during braking, reducing the risk of brake fade. The directional smooth surface ensures consistent pad contact and braking performance. With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, the rotor provides clear wear limits for maintenance. The GEOMET grey coating on the hat offers rust resistance, extending the rotor's service life. The rotor includes five bolt holes with a diameter of 16.7 mm and a bolt circle diameter of 112 mm, compatible with the specified BMW and Mini models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped disc brakes on BMW 228i xDrive Gran Coupe and Mini Cooper models\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by overheating through vented rotor design\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor damage with rust-resistant GEOMET coating\u003c\/li\u003e\n\u003cli\u003eRestores smooth braking performance by maintaining proper rotor thickness and surface finish\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicles requiring a directional rotor surface for optimal pad engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 28.4 mm. Clean the rotor surface to remove any protective coatings or contaminants before mounting to ensure proper pad contact.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 900-31184D rotor to meet OEM specifications for fitment and performance on BMW and Mini vehicles.
