This product line is designed to provide consistent braking performance under demanding conditions, making it suitable for Audi A4 and A4 Quattro drivers seeking reliable rotor upgrades.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring durability and safety throughout its service life. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, reducing brake fade and maintaining consistent stopping power. The directional surface design further optimizes braking efficiency by channeling debris away from the contact area.\u003c\/p\u003e\u003cp\u003eThe rotor measures 287 mm in outside diameter and 36 mm in overall height, fitting precisely on the hub with a center hole diameter of 68 mm. It features a Geospec silver grey hat finish that includes a rust-resistant coating to protect against corrosion and extend rotor life. The 5-bolt hole pattern with a 112.2 mm bolt circle diameter matches the factory specifications for Audi A4 and A4 Quattro models, ensuring proper fitment and installation.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance for Audi A4 and A4 Quattro vehicles\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eMinimizes heat buildup with drilled and slotted design\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion with protective coating\u003c\/li\u003e\n\u003cli\u003eMaintains consistent brake pad contact and bite\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on compatible Audi A4 or A4 Quattro models matching the 5-lug, 112.2 mm bolt circle pattern. Verify rotor thickness before installation; replace if below the discard thickness of 10 mm. Clean the rotor surface before mounting to remove any protective oils. Proper torque specifications should be followed for lug nuts to avoid warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet or exceed OEM standards for fit, form, and function.
