The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of BMW vehicles requiring reliable vented rotors with directional braking surfaces for enhanced control and safety.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The rotor’s surface is both drilled and slotted, which helps evacuate gases, dust, and water from the braking surface, improving pad contact and braking consistency. The directional design ensures the rotor is installed correctly for optimal performance. The rotor’s nominal thickness is 21.8 mm, with a discard thickness of 20.4 mm, indicating when replacement is necessary. The zinc black finish on the hat offers rust resistance, maintaining structural integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance on BMW 330Ci, 330i, and 330xi models\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eMinimizes rotor warping caused by excessive heat\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent brake pad contact and bite\u003c\/li\u003e\n\u003cli\u003eProtects against corrosion with rust-resistant coating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle diameter pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 20.4 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for BMW 330Ci, 330i, and 330xi models. The rust-resistant zinc black finish and vented design contribute to durability and performance consistency. While no specific warranty information is provided, the rotor is engineered for reliable service life under normal operating conditions.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51797403992245,"sku":"HBHR-633-31053L","price":105.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63331053L_Fro.jpg?v=1774641900","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-633-31053l-disc-brake-rotor-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
