The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life under typical driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented and directional, with a surface that combines both drilled holes and slots to improve water and dust evacuation from the braking surface. The rotor has a nominal thickness of 18 mm and a discard thickness of 16 mm, ensuring safe replacement intervals. The rotor’s overall diameter measures 324 mm with a height of 56 mm, and it features a center hole diameter of 72 mm. The zinc silver coating on the hat area offers rust resistance, which is critical for maintaining rotor integrity over time. The rotor includes five bolt holes with a bolt circle diameter of 114.3 mm, matching the Mazda CX-9’s specifications.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Mazda CX-9\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust resistant coating\u003c\/li\u003e\n\u003cli\u003eRestores proper braking surface for enhanced safety and control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 16 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the Mazda CX-9 hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-80068L rotor to meet OEM specifications for fit and function on Mazda CX-9 vehicles. The rust resistant zinc silver finish helps extend rotor life by reducing corrosion. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and braking performance under normal operating conditions.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51726977040565,"sku":"HBHR-631-80068L","price":112.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63180068L_Fro.jpg?v=1774640283","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-80068l-disc-brake-rotor-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
