This design helps to reduce brake fade by allowing gases and debris to escape, while the zinc silver hat finish offers enhanced protection against rust and corrosion. This rotor line is tailored for vehicles requiring precise fitment and durability, such as the Hyundai K5 and Kia Sonata.\u003c\/p\u003e\u003ch2\u003eProduct Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a 325 mm outside diameter and a nominal thickness of 12 mm, with a discard thickness set at 10 mm to ensure safe replacement intervals. The rotor’s directional surface combines drilled holes and slots to optimize heat dissipation and maintain consistent braking performance. The zinc silver hat finish and rust-resistant coating extend the rotor’s service life by protecting against environmental wear. The rotor mounts with five bolt holes, each 12.6 mm in diameter, arranged on a 114.3 mm bolt circle diameter, ensuring compatibility with specified Hyundai and Kia models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Hyundai K5 and Kia Sonata models requiring 325 mm rotors\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by overheating during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake dust and debris buildup on rotor surface\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion for longer rotor lifespan\u003c\/li\u003e\n\u003cli\u003eMaintains braking efficiency 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 10 mm before installation. Properly clean the rotor surface to remove any protective coatings or contaminants. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 114.3 mm bolt circle pattern. Use appropriate torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed following the indicated rotation direction 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 Hyundai and Kia vehicles. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor’s design and materials support reliable, long-term braking performance when installed and maintained correctly.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794110251189,"sku":"HBHR-631-21049L","price":113.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63121049L_Fro.jpg?v=1774641325","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-21049l-disc-brake-rotor-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
