The vented rotor construction allows for efficient heat dissipation during braking, reducing the risk of warping under high temperatures. The dimpled and slotted surface pattern improves pad contact and helps evacuate gases and debris, contributing to consistent brake performance. With a 345 mm outside diameter and a 24 mm nominal thickness, this rotor maintains structural integrity and durability over time. The five bolt holes with a 16.6 mm diameter and 75 mm inside diameter ensure a secure and exact fit on compatible BMW models.\u003c\/p\u003e\u003ch2\u003eCompatible BMW Models and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBMW 230i and 230i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 328i\u003c\/li\u003e\n\u003cli\u003eBMW 330i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 335i and 335i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 340i and 340i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 428i, 428i Gran Coupe, and 428i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 430i and 430i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 435i, 435i Gran Coupe, 435i xDrive, and 435i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003eBMW 440i, 440i Gran Coupe, 440i xDrive, and 440i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003eBMW ActiveHybrid 3\u003c\/li\u003e\n\u003cli\u003eBMW M240i and M240i xDrive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by excessive heat buildup during aggressive driving\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to rotor surface imperfections\u003c\/li\u003e\n\u003cli\u003eWarped rotors resulting in vibration or pulsation during braking\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency from glazed or contaminated rotors\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust buildup on rotor surfaces affecting performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor discard thickness of 22.4 mm is not exceeded before replacement\u003c\/li\u003e\n\u003cli\u003eClean mounting surface and hub to prevent rotor runout\u003c\/li\u003e\n\u003cli\u003eTorque bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and calipers during installation for optimal performance\u003c\/li\u003e\n\u003cli\u003ePerform a bed-in procedure after installation to maximize rotor and pad contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC GEOSPEC Coated Rotor - Dimpled and Slotted to meet strict quality standards for durability and performance.
