The rotor has a nominal thickness of 0.75 inches (19 mm) and a discard thickness of 0.69 inches (17.4 mm), indicating when replacement is necessary to maintain safe braking. Its overall height measures 2.38 inches (60.5 mm), and the outside diameter is 11.57 inches (294 mm), matching OEM specifications for the BMW 325xi. The rotor includes five mounting bolt holes arranged in a 120 mm bolt circle diameter, with each hole measuring 0.58 inches (14.7 mm) in diameter. The center hole diameter is 2.95 inches (75 mm), ensuring proper hub fitment. This rotor does not include an ABS tone ring and is not cross-drilled or slotted, focusing on standard braking performance without additional features.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is specifically compatible with BMW 325xi models, providing a direct replacement for worn or damaged rotors. It is designed to work with vehicles equipped with drum-in-hat type rotors, integrating the parking brake mechanism within the rotor assembly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors causing vibration or noise\u003c\/li\u003e\n\u003cli\u003eRestores braking efficiency and pedal feel\u003c\/li\u003e\n\u003cli\u003eAddresses rotor thickness below discard limits\u003c\/li\u003e\n\u003cli\u003eEliminates brake judder and uneven pad wear\u003c\/li\u003e\n\u003cli\u003eSupports proper parking brake operation with drum-in-hat design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the DuraGo BR900778 rotor on a BMW 325xi, ensure the rotor surface is clean and free of any protective coatings or debris before mounting. Verify that the rotor thickness meets or exceeds the nominal thickness specification. Use proper torque settings on the five mounting bolts to secure the rotor firmly. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty Information\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures this disc brake rotor to meet or exceed OEM standards for fit, form, and function. The cast iron construction provides consistent heat dissipation and durability under normal driving conditions. While this rotor does not feature a rust-resistant coating, proper maintenance and installation will help extend its service life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.\u003c\/p\u003e","brand":"DuraGo","offers":[{"title":"Default Title","offer_id":43585109196981,"sku":"GVMP-BR900778","price":46.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/PR_BR900778_Fro.jpg?v=1774635038","url":"https:\/\/www.partcatalog.com\/products\/durago-br900778-disc-brake-rotor","provider":"PartCatalog","version":"1.0","type":"link"}
