This design improves water and gas evacuation from the rotor surface, enhancing braking consistency and reducing the risk of brake fade. The silver zinc coating on the rotor hat provides additional corrosion resistance, extending the rotor's service life in various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that promotes airflow between the rotor surfaces, helping to dissipate heat generated during braking. The rotor's surface is both drilled and slotted in a directional pattern, which aids in removing brake dust, gases, and moisture for improved pad bite and consistent braking performance. The rotor's nominal thickness is 22 mm, with a discard thickness of 20.4 mm, ensuring clear wear limits for safe operation. The rotor includes five bolt holes with a diameter of 15 mm and a bolt circle diameter of 120 mm, matching the OEM specifications for the compatible BMW models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 3 Series and Z models\u003c\/li\u003e\n\u003cli\u003eImproves braking performance under wet or high-temperature conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during aggressive or extended driving\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eProtects against rust and corrosion for longer rotor life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 20.4 mm to maintain safe braking performance. Use proper torque specifications for the 5 lug bolts with 15 mm diameter and 120 mm bolt circle diameter. Directional rotors must be installed with the correct rotation direction to maintain optimal performance and longevity.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31027R rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliable braking performance for BMW 318i, 320i, 325i, 328i, Z3, and Z4 vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794113069237,"sku":"HBHR-631-31027R","price":85.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63131027R_Fro.jpg?v=1774641349","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-31027r-disc-brake-rotor-front-right","provider":"PartCatalog","version":"1.0","type":"link"}
