This design improves heat dissipation and reduces brake fade, while the directional surface pattern ensures consistent pad contact and effective water and debris evacuation. The rotors in this line are vented to further enhance cooling, making them suitable for both daily driving and spirited use on compatible BMW vehicles.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a 348 mm outside diameter and a height of 66.6 mm, designed to meet the exacting standards of BMW braking systems. The rotor is vented to allow airflow between the rotor faces, reducing heat buildup during braking. The directional drilled and slotted surface improves pad bite and helps maintain clean contact surfaces by channeling away dust and gases. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance along with a rust resistant coating applied to the entire rotor surface. The 5 bolt holes with a 16.7 mm diameter and a 112 mm bolt circle diameter ensure precise mounting compatibility with the specified BMW models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eImproves braking response and pad bite on BMW 330i and 530i models\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eMinimizes corrosion and rust formation for longer rotor life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance in wet or debris-prone conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on compatible BMW models listed in the fitment section. Verify the rotor thickness before installation; replace if below the discard thickness of 28.4 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Use proper torque specifications for the 5 lug bolts to avoid warping. Directional rotors must be installed with the rotation arrow pointing in the correct direction of wheel rotation for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction rotors undergo rigorous quality control to meet OEM standards for fit, finish, and performance. The rust resistant coating and Geospec silver grey hat finish provide added durability against corrosion. While no specific warranty information is provided, Dynamite Friction products are manufactured to maintain consistent braking performance and reliability on compatible BMW vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51801077776565,"sku":"HBHR-830-31168L","price":149.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_83031168L_Fro.jpg?v=1774642305","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-830-31168l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
