Designed as a vented disc brake rotor, it offers reliable heat dissipation and consistent stopping power for vehicles like the BMW 325xi, 328i, 328i xDrive, 328xi, and X1.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNominal thickness: 20 mm\u003c\/li\u003e\n\u003cli\u003eDiscard thickness: 18.4 mm\u003c\/li\u003e\n\u003cli\u003eOutside diameter: 300 mm\u003c\/li\u003e\n\u003cli\u003eInside diameter: 75 mm\u003c\/li\u003e\n\u003cli\u003eBolt hole diameter: 14.5 mm\u003c\/li\u003e\n\u003cli\u003eBolt hole quantity: 5\u003c\/li\u003e\n\u003cli\u003eHeight: 66.2 mm\u003c\/li\u003e\n\u003cli\u003eVented rotor design for improved cooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that enhances airflow to reduce heat buildup during braking, which is critical for maintaining brake efficiency and preventing warping. The rotor’s 300 mm outside diameter and 20 mm nominal thickness provide a solid braking surface, while the discard thickness of 18.4 mm indicates the minimum safe thickness before replacement is necessary. With five bolt holes measuring 14.5 mm in diameter, this rotor is compatible with the specified BMW models, ensuring proper fitment and secure installation. The 66.2 mm height and 75 mm inside diameter are engineered to match the original equipment specifications for these vehicles.\u003c\/p\u003e\u003ch2\u003eDFC GEOSPEC Coated Rotor Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on rotors with specialized coatings designed to resist corrosion and extend rotor life. This coating helps maintain rotor integrity and appearance over time, especially in environments prone to moisture and road salt exposure. The 604-31081 rotor benefits from this coating, providing durability and consistent braking performance for BMW 325xi, 328i, 328i xDrive, 328xi, and X1 models.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 325xi and 328i models\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency in vented rotor applications\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor damage with specialized coating\u003c\/li\u003e\n\u003cli\u003eMaintains proper brake pad contact for enhanced stopping power\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Dynamite Friction DFC GEOSPEC Coated Rotor 604-31081, ensure the rotor is compatible with your BMW model’s bolt pattern and dimensions. Clean the hub surface before mounting to prevent runout and ensure proper seating. Torque the bolts to manufacturer specifications and inspect brake pads for wear to optimize braking performance.
