The nominal thickness measures 28.0 mm (1.102 inches) with a discard thickness of 26.4 mm (1.039 inches), ensuring precise wear limits for safe operation. The rotor features a vented design with curved vanes that promote efficient cooling during heavy braking. The hat section is coated to protect against rust and corrosion, maintaining structural integrity over time. The rotor mounts using a floating disc system with a 120 mm (4.724 inches) bolt circle diameter and five lug holes sized at 14.8 mm (0.583 inches) diameter. The center hole diameter is 79 mm (3.110 inches), designed to fit BMW M3 hubs accurately. This rotor weighs approximately 8.65 kg (19.04 lbs), balancing durability and performance.\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 through improved heat management and pad bite. The combination of cross-drilled holes and slots helps to evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent stopping power. This product line is suitable for performance-oriented vehicles like the BMW M3, where reliable braking under demanding conditions is essential.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive driving or track use\u003c\/li\u003e\n\u003cli\u003eImproves wet weather braking by channeling water away from the rotor surface\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust buildup for cleaner rotor and pad contact\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent brake pedal feel under heavy use\u003c\/li\u003e\n\u003cli\u003ePrevents rotor warping through efficient heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure compatibility with BMW M3 models requiring 325 mm rotors before installation\u003c\/li\u003e\n\u003cli\u003eInspect hub and mounting surfaces for cleanliness and damage prior to installation\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications to avoid rotor distortion\u003c\/li\u003e\n\u003cli\u003eReplace brake pads simultaneously to ensure optimal rotor performance\u003c\/li\u003e\n\u003cli\u003ePerform a proper bed-in procedure after installation for best braking 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 specifications for fit, form, and function.
