The dimpled and slotted surface pattern enhances pad bite and helps channel away dust and gases generated under heavy braking. With a nominal thickness of 24 mm and a discard thickness of 22.4 mm, this rotor maintains structural integrity and performance throughout its service life. The rotor’s 344 mm outside diameter and 66.3 mm height are engineered to fit precisely on compatible BMW models, ensuring proper installation and function.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Dimpled and Slotted Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Dimpled and Slotted line by Dynamite Friction focuses on rotors that combine vented construction with surface dimpling and slotting. This design improves braking efficiency by increasing friction surface area and aiding in heat and debris management. The 640-31113 rotor is part of this line, tailored to meet the demands of performance-oriented BMW vehicles requiring reliable stopping power and rotor durability.\u003c\/p\u003e\u003ch2\u003eCompatible BMW Models and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with BMW 118i, 120i, 230i, 230i xDrive\u003c\/li\u003e\n\u003cli\u003eFits BMW 328i, 428i, M135i, M140i\u003c\/li\u003e\n\u003cli\u003eSuitable for BMW M235i, M235i xDrive, M240i, M240i xDrive\u003c\/li\u003e\n\u003cli\u003eDesigned for vehicles requiring a 5-bolt rotor with 16.6 mm bolt hole diameter\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 overheating during aggressive driving\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to rotor surface irregularities\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency from dust and gas buildup\u003c\/li\u003e\n\u003cli\u003eVibration or pulsation from warped or worn rotors\u003c\/li\u003e\n\u003cli\u003eCompatibility issues with OEM brake components on specified BMW models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (22.4 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface to remove any protective coatings or debris\u003c\/li\u003e\n\u003cli\u003eTorque wheel bolts to manufacturer specifications for BMW models\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and calipers for wear or damage during rotor replacement\u003c\/li\u003e\n\u003cli\u003ePerform a bed-in procedure after installation to optimize rotor and pad performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 640-31113 rotor to meet strict quality standards for durability and performance.
