The rotor features a directional surface with both drilled holes and slots, which help to improve heat dissipation and reduce brake fade during extended use. The rotor’s nominal thickness is 10 mm, with a discard thickness of 8.4 mm, ensuring it maintains structural integrity over its service life.\u003c\/p\u003e\u003cp\u003eThe rotor’s hat is finished with a zinc silver coating, providing enhanced resistance to rust and corrosion, which is further supported by an overall rust-resistant coating. The rotor is designed with five bolt holes, each 12.4 mm in diameter, arranged on a 114.3 mm bolt circle diameter, making it compatible with the specified Hyundai and Kia models. The 302 mm outside diameter and 31.2 mm height ensure proper fitment and performance.\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 from Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This product line is engineered to provide consistent braking performance and durability, particularly for vehicles requiring directional rotors that aid in heat management and debris removal. The silver zinc coating on the hat enhances longevity by protecting against rust, making it suitable for various driving conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade caused by overheating during heavy braking\u003c\/li\u003e\n\u003cli\u003eImproves water and debris evacuation for consistent braking in wet conditions\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on the rotor surface and hat\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity with clear discard thickness guidelines\u003c\/li\u003e\n\u003cli\u003eEnsures proper fitment for Hyundai Nexo, Sportage, and Tucson models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor thickness before installation; replace if below 8.4 mm discard thickness\u003c\/li\u003e\n\u003cli\u003eEnsure bolt hole alignment matches the 5-lug, 114.3 mm bolt circle diameter pattern\u003c\/li\u003e\n\u003cli\u003eClean rotor surface before installation to remove any protective coatings or residues\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for lug nuts to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle model and year for optimal fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-21042R rotor to meet industry standards for durability and performance.
