Its vented rotor construction allows for efficient heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The rotor surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact and improving overall braking response.\u003c\/p\u003e\u003cp\u003eThe rotor features a plain disc finish combined with a zinc silver hat finish that includes a rust-resistant coating, extending the rotor's service life by protecting against corrosion. With a nominal thickness of 24 mm and a discard thickness of 22.4 mm, this rotor ensures durability and safety throughout its lifespan. The 345 mm outside diameter and 63.2 mm overall height are engineered for exact fitment on compatible BMW models, while the 5 bolt holes with a 14.5 mm diameter and 120 mm bolt circle diameter provide secure mounting.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors that combine enhanced braking performance with corrosion resistance. The drilled and slotted design improves heat dissipation and pad bite, while the zinc silver hat finish with rust-resistant coating helps maintain rotor integrity over time. This product line is tailored for drivers seeking reliable, performance-oriented rotors for their BMW vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 535i, 545i, 550i, 645Ci, and 650i\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by reducing brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion that can compromise rotor lifespan\u003c\/li\u003e\n\u003cli\u003eEnhances brake pad contact and debris removal for consistent stopping power\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 22.4 mm before installation. The rotor is directional, so proper orientation during installation is critical for optimal performance. Verify the bolt hole pattern matches your vehicle’s specifications: 5 bolt holes with a 14.5 mm diameter and 120 mm bolt circle diameter. Clean the rotor surface before mounting to remove any protective coatings or residues. Use appropriate torque specifications for the lug nuts to avoid rotor warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31064R rotor to meet OEM standards for fit, form, and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance and resist corrosion under normal operating conditions.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794115231925,"sku":"HBHR-631-31064R","price":115.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63131064R_Fro.jpg?v=1774641364","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-31064r-disc-brake-rotor-rear-right","provider":"PartCatalog","version":"1.0","type":"link"}
