This design improves water and gas evacuation during braking, reducing brake fade and maintaining consistent performance. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively. The rotor's directional surface pattern, featuring both drilled holes and slots, helps maintain optimal brake pad contact and removes dust and gases generated during braking. The rotor measures 328 mm in outside diameter with a height of 61 mm, and it includes five bolt holes with a diameter of 14.7 mm arranged on a 120 mm bolt circle diameter. The nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring safe replacement intervals.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on BMW 750iL and Z8\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during extended braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet conditions by evacuating water\u003c\/li\u003e\n\u003cli\u003eReduces brake dust buildup on rotor surface for cleaner operation\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion with zinc silver coated rotor hat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is compatible with your BMW 750iL or Z8 by verifying part number 631-31041L before installation. Clean the hub surface thoroughly to ensure proper rotor seating. Follow manufacturer torque specifications for the 5 lug bolts with 14.7 mm diameter. Because this rotor is directional, confirm the correct orientation during installation to maintain optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust-resistant coating on the rotor hat helps extend service life. While no specific warranty information is provided, the rotor is designed for reliable performance and durability when installed and maintained according to manufacturer guidelines.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51810602385589,"sku":"HBHR-631-31041L","price":109.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63131041L_Fro.jpg?v=1774642938","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-31041l-disc-brake-rotor-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
