This rotor features a vented design, which allows air to flow between the rotor surfaces, reducing heat buildup during braking. The nominal thickness of 0.94 inches (24 mm) ensures a solid braking surface, while the discard thickness of 0.88 inches (22.4 mm) indicates when replacement is necessary to maintain safety and performance. With an outside diameter of 12.99 inches (330 mm) and a center hole diameter of 3.11 inches (79 mm), this rotor is designed to fit BMW 130i, 330i, and 330xi models precisely. The rotor includes five mounting bolt holes with a 4.72-inch (120 mm) bolt circle diameter, ensuring secure attachment to the wheel hub.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis DuraGo disc brake rotor is compatible with the following BMW models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW 130i\u003c\/li\u003e\n\u003cli\u003eBMW 330i\u003c\/li\u003e\n\u003cli\u003eBMW 330xi\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIt is designed for use in conventional braking systems without ABS tone rings and features a non-directional brake surface, allowing for flexible installation on either side of the vehicle.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation caused by warped rotors\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency due to worn rotor thickness\u003c\/li\u003e\n\u003cli\u003eOverheating and brake fade from insufficient heat dissipation\u003c\/li\u003e\n\u003cli\u003eNoise and vibration from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eCorrosion-related rotor damage (note: this rotor does not include rust-resistant coating)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the DuraGo BR900666 rotor, ensure the rotor surface is clean and free of debris before mounting. Verify that the rotor thickness is above the discard limit of 0.88 inches (22.4 mm) to maintain safe braking performance. Use proper torque specifications for the five mounting bolts to avoid rotor warping. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. While this rotor does not feature a rust-resistant coating, its full cast iron construction provides reliable durability under normal operating conditions.
