The combination of cross-drilled holes and precision slots helps to evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent pedal feel. The vented rotor design further aids in heat dissipation, making these rotors suitable for spirited driving and daily use on Mazda 3 vehicles.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented construction with straight vane style to optimize airflow and cooling. The rotor’s overall height measures 48.5 mm (1.909 inches), and it includes a coated hat finish to protect against corrosion and extend service life. The center hole diameter is 72 mm (2.835 inches), and the rotor mounts using a floating disc system to reduce stress and improve durability. It is designed with 5 lug holes, each 13.8 mm (0.543 inches) in diameter, arranged on a 114.3 mm (4.5 inches) bolt circle diameter.\u003c\/p\u003e\u003ch2\u003eApplications 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 prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eEnhances brake pad bite and responsiveness\u003c\/li\u003e\n\u003cli\u003eHelps remove brake dust and debris for cleaner braking surfaces\u003c\/li\u003e\n\u003cli\u003eResists corrosion with coated hat finish for longer rotor life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure compatibility with Mazda 3 models before installation. Verify rotor thickness and discard thickness to confirm rotor condition if replacing. Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle. The floating disc mounting requires careful alignment to avoid uneven wear. It is recommended to replace brake pads when installing new rotors to ensure optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
