This product line is designed to provide enhanced braking performance and durability, particularly for vehicles like the Mazda RX-7 that demand consistent stopping power. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The rotor's surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking efficiency and reducing the risk of brake fade. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, indicating when replacement is necessary to maintain safe braking performance.\u003c\/p\u003e\u003cp\u003eThe rotor's hat is finished with a zinc silver coating that provides rust resistance, an important feature for maintaining rotor integrity over time. It features five bolt holes with a bolt circle diameter of 114.3 mm, matching the Mazda RX-7's specifications. The overall height and height of the rotor are both 67 mm, with a center hole diameter of 72 mm and stud\/lug hole diameter of 13 mm.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped brake rotors on Mazda RX-7 models\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eImproves braking response in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake noise and vibration through slotted and drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on rotor hats for longer service life\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 20 mm before installation. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify bolt hole alignment with the Mazda RX-7 hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Mazda RX-7 vehicles. The rust-resistant zinc silver coating on the rotor hat helps maintain durability in various driving conditions. While no specific warranty information is provided, the rotor's design and materials support reliable braking performance when installed and maintained properly.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795678888117,"sku":"HBHR-631-80031R","price":100.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63180031R_Fro.jpg?v=1774641800","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-80031r-disc-brake-rotor-front-right","provider":"PartCatalog","version":"1.0","type":"link"}
