These rotors provide reliable braking performance with a vented, cross-drilled design to help maintain consistent stopping power under demanding conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCross-drilled surface for improved heat dissipation\u003c\/li\u003e\n\u003cli\u003eVented rotor design to reduce brake fade\u003c\/li\u003e\n\u003cli\u003eCoated hat finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eFloating disc mounting for enhanced rotor alignment\u003c\/li\u003e\n\u003cli\u003eCompatible with 5-lug wheel setups on specified BMW models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Product Features and Specifications\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled Disc Brake Rotors feature a vented design with straight vanes that promote efficient airflow and cooling during braking. The cross-drilled surface pattern helps to dissipate heat and gases generated during heavy braking, reducing the risk of brake fade. The rotor has a coated hat finish to protect against corrosion and extend service life. With an outside diameter of 324 mm (12.756 inches) and an overall height of 77.2 mm (3.039 inches), these rotors are designed to meet the exact specifications required for BMW 5 Series models listed in the fitment.\u003c\/p\u003e\u003cp\u003eThe rotor thickness is nominally 30.0 mm (1.181 inches) with a discard thickness of 28.4 mm (1.118 inches), ensuring safe replacement intervals. The center hole diameter measures 79.0 mm (3.110 inches), and the mounting bolt hole circle diameter is 120.0 mm (4.724 inches) with five stud\/lug holes sized at 14.6 mm (0.575 inches). This part does not include ABS tone rings or bearings and uses a floating disc mounting system to allow for slight rotor movement, which can improve braking consistency.\u003c\/p\u003e\u003ch2\u003eAbout the StopTech Sport Cross-Drilled Disc Brake Rotors Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance for sport and performance-oriented vehicles. This product line focuses on improving heat dissipation and reducing brake fade through cross-drilled rotor surfaces and vented designs. The rotors are engineered to meet or exceed OEM specifications, making them suitable for BMW 5 Series models requiring reliable and consistent braking under various driving conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to maintain rotor integrity\u003c\/li\u003e\n\u003cli\u003eMinimizes corrosion with coated hat finish\u003c\/li\u003e\n\u003cli\u003eAddresses rotor warping issues with vented and floating design\u003c\/li\u003e\n\u003cli\u003eCompatible replacement for worn or damaged OEM rotors 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 discard thickness is not exceeded before installation\u003c\/li\u003e\n\u003cli\u003eVerify compatibility with vehicle’s lug pattern and bolt circle diameter\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and calipers during rotor replacement\u003c\/li\u003e\n\u003cli\u003ePerform a bed-in procedure after installation for optimal braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech Sport Cross-Drilled Disc Brake Rotors are manufactured to meet strict quality standards and OEM specifications.
