The zinc black hat finish provides corrosion resistance, extending rotor life. This product line focuses on delivering reliable braking performance for specific vehicle applications, including the BMW 135i and 135is.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow and heat management during braking. The rotor’s surface is both drilled and slotted, which helps reduce brake fade by allowing gases and debris to escape. The directional surface design ensures optimal contact with brake pads for consistent stopping power. The rotor measures 324 mm in outside diameter with a nominal thickness of 21.8 mm and a discard thickness of 20.4 mm, ensuring it meets OEM standards for durability and performance. The zinc black coating on the hat area provides rust resistance, maintaining structural integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped rotors on BMW 135i and 135is\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eAddresses corrosion issues with rust resistant coating\u003c\/li\u003e\n\u003cli\u003eEnhances braking response with directional drilled and slotted design\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 20.4 mm before installation. Clean the rotor surface to remove any protective coating before mounting. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle pattern specific to BMW 135i and 135is. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust resistant zinc black finish helps extend rotor life by preventing corrosion. While no specific warranty information is provided, Dynamite Friction products are generally backed by quality control standards to ensure reliable braking performance on BMW 135i and 135is vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51797406122165,"sku":"HBHR-633-31090R","price":118.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63331090R_Fro.jpg?v=1774641909","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-633-31090r-disc-brake-rotor-rear-right","provider":"PartCatalog","version":"1.0","type":"link"}
