The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is designed to meet the demands of BMW vehicles requiring reliable stopping power and consistent performance under various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.4 mm, ensuring it meets safety standards for wear limits. The directional slotted and drilled surface enhances water and gas evacuation from the braking surface, which helps maintain consistent braking performance. The rotor's bolt pattern includes four 15 mm diameter holes on a 100 mm bolt circle diameter, matching the fitment requirements for the specified BMW models. The zinc black hat finish with rust-resistant coating protects against corrosion, which is critical for longevity in diverse environments.\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 318i, 318is, 325e, 325es, 325i, 325is, and 325iX\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eMaintains braking efficiency in wet conditions through drilled and slotted design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on rotor hats for extended 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 8.4 mm before installation. Clean the rotor surface to remove any protective coating or debris before mounting. Verify bolt hole alignment with the vehicle’s hub using the 100 mm bolt circle diameter and 15 mm bolt hole 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 this rotor to meet OEM specifications for fit and function on compatible BMW models. The rust-resistant zinc black coating on the rotor hat enhances durability. While no specific warranty information is provided, the rotor’s design and materials comply with industry standards for safety and performance.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51797403205813,"sku":"HBHR-633-31018L","price":84.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63331018L_Fro.jpg?v=1774641888","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-633-31018l-disc-brake-rotor-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
