The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes airflow to maintain optimal operating temperatures. The zinc silver hat finish adds corrosion resistance, extending rotor life especially in humid or wet environments.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design with a 239 mm outside diameter and a 38.6 mm overall height, tailored for select Audi and Volkswagen vehicles including the 4000, Cabriolet, Coupe, Derby, Golf, Jetta, and Rabbit Convertible models. The rotor’s surface is both drilled and slotted, providing directional braking surfaces that improve pad bite and reduce heat buildup. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, helping maintain structural integrity and appearance over time. The rotor includes 4 bolt holes with a 100 mm bolt circle diameter and a center hole diameter of 65 mm, matching factory specifications for proper fitment.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Audi and Volkswagen models such as Golf, Jetta, and Cabriolet\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat during aggressive driving\u003c\/li\u003e\n\u003cli\u003eReduces brake dust and debris buildup with slotted and drilled surface\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping through vented design and heat dissipation\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency in wet or corrosive environments with rust-resistant coating\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 18 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify bolt hole alignment with the 4-lug, 100 mm bolt circle diameter pattern. Use proper torque specifications for lug nuts to avoid rotor distortion. Directional rotors should be installed following the indicated rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver hat finish enhances durability against corrosion. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliable braking performance on compatible Audi and Volkswagen vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795665846453,"sku":"HBHR-631-74004L","price":67.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63174004L_Fro.jpg?v=1774641720","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-74004l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
