The rotors have an overall height of 2.618 inches (66.500 mm) and an outside diameter of 13.701 inches (348.000 mm), designed to meet exact OEM specifications for proper fitment. The vented rotor type improves airflow to reduce heat buildup during aggressive braking. The hat section is coated to resist corrosion, extending the rotor’s durability. This rotor includes a floating disc mounting system, which helps maintain optimal rotor alignment and reduces the risk of warping under high stress. The rotor is designed with five stud\/lug holes, each with a diameter of 0.654 inches (16.600 mm), and a mounting bolt hole circle diameter of 4.724 inches (120.000 mm). The center hole diameter measures 2.953 inches (75.000 mm), ensuring precise fitment on compatible BMW hubs.\u003c\/p\u003e\u003ch2\u003eAbout the StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for sport and performance vehicles. Featuring a combination of cross-drilled holes and slots, these rotors improve heat dissipation and help evacuate gases and debris from the braking surface. This design reduces brake fade and maintains consistent pedal feel during demanding driving conditions. The vented rotor construction further aids in cooling, making this product line suitable for BMW models that require reliable and efficient braking under both street and spirited driving scenarios.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during high-performance or aggressive driving\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eHelps remove brake dust and debris for cleaner braking surfaces\u003c\/li\u003e\n\u003cli\u003eEnhances braking consistency and pedal feel\u003c\/li\u003e\n\u003cli\u003eProvides corrosion resistance with coated hat finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor discard thickness is checked before installation to confirm suitability\u003c\/li\u003e\n\u003cli\u003eVerify compatibility with BMW 535d, 535i, 640i, and ActiveHybrid 5 models\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts to avoid rotor damage\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and hardware during rotor replacement for optimal performance\u003c\/li\u003e\n\u003cli\u003eFloating disc mounting requires correct alignment for best results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech disc brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
