The drilled and slotted design helps maintain consistent braking performance under demanding conditions, making it suitable for Audi vehicles requiring reliable stopping power.\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, reducing the risk of brake fade during extended use. The rotor's nominal thickness is 24.8 mm, with a discard thickness of 23 mm, ensuring a clear maintenance threshold. The rotor surface is both drilled and slotted, which aids in water and gas evacuation from the braking surface, improving pad bite and overall braking response. The zinc silver hat finish provides rust resistance, extending the rotor's service life. With a 5-bolt hole pattern and a 112 mm bolt circle diameter, this rotor fits securely on compatible Audi models. The directional brake surface is designed to optimize braking efficiency and pad contact.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Audi A4, A4 Quattro, A5, A5 Quattro, and A5 Sportback\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion with zinc silver coating\u003c\/li\u003e\n\u003cli\u003eEnhances braking performance in wet conditions through drilled and slotted design\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking feel and pad contact with directional surface\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 23 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify the 5-bolt hole pattern and 112 mm bolt circle diameter match your vehicle’s hub. Properly torque lug nuts to manufacturer specifications 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 the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM specifications for fit and function. The rust resistant zinc silver hat finish helps extend rotor life. While no specific warranty information is provided, the rotor is designed for durability and consistent braking performance on compatible Audi models.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795665780917,"sku":"HBHR-631-73086L","price":116.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63173086L_Fro.jpg?v=1774641719","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-73086l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
