The drilled and slotted surface design helps reduce brake fade by allowing gases and heat to escape more effectively. The zinc silver hat finish and rust resistant coating provide added protection against corrosion, making this rotor suitable for BMW models that demand reliable stopping power under varied driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis rotor features a vented design with an overall height of 66.2 mm, which improves airflow and heat dissipation during braking. The directional slotted and drilled surface optimizes braking performance by channeling water and debris away from the contact area. With a bolt circle diameter of 120 mm and five lug holes sized at 16.6 mm, it is specifically engineered for BMW vehicles including the 230i, 328i xDrive, 340i, and M240i xDrive among others. The nominal thickness of 24 mm ensures durability, while the discard thickness of 22.4 mm indicates when replacement is necessary to maintain safety and performance.\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 328d xDrive, 328i, and 328i xDrive\u003c\/li\u003e\n\u003cli\u003eBMW 330i xDrive and 335i variants\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, 430i xDrive, 435i, and 435i Gran Coupe\u003c\/li\u003e\n\u003cli\u003eBMW 440i, 440i Gran Coupe, and 440i xDrive models\u003c\/li\u003e\n\u003cli\u003eBMW ActiveHybrid 3, M240i, and M240i xDrive\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 mounting surface to prevent rotor runout\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications for BMW models\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and calipers\u003c\/li\u003e\n\u003cli\u003eFollow proper bedding-in procedures after installation for optimal performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31114L rotor with rust resistant coatings and zinc silver hat finish to enhance durability and corrosion resistance.
