The vented rotor design incorporates straight vanes that promote airflow to cool the rotor during aggressive driving or track use. The cross-drilled and slotted surface pattern helps to evacuate gases and debris from the brake pad interface, improving braking consistency and reducing the risk of brake fade. The coated hat finish protects the rotor hub from rust and corrosion, maintaining structural integrity over time.\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 enhance braking performance through advanced rotor surface technology and durable construction. This product line focuses on improving heat dissipation and pad bite by combining cross-drilled holes with precision-machined slots. These rotors are vented and coated to provide a balance of performance and longevity, making them suitable for both spirited street driving and occasional track use.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during high-performance or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves pad bite and braking response in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eMinimizes rotor warping caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance for Mazda RX-8 vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness of 16.0mm before installation\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for the 5 lug bolts on the 114.3mm bolt circle\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and calipers on Mazda RX-8\u003c\/li\u003e\n\u003cli\u003eClean rotor surface with brake cleaner before installation to remove any protective coatings\u003c\/li\u003e\n\u003cli\u003eAllow a proper bedding-in period after installation for optimal brake performance\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.
