The drilled and slotted surface helps evacuate gases, dust, and water from the braking surface, reducing brake fade and improving wet weather performance. The vented rotor construction allows air to flow between the rotor faces, aiding in heat dissipation during heavy braking.\u003c\/p\u003e\u003cp\u003eThe rotor features a plain disc finish combined with a zinc silver rust-resistant coating on the hat, providing corrosion protection and maintaining structural integrity over time. With a nominal thickness of 22mm and a discard thickness of 20mm, this rotor meets strict wear specifications to ensure safe replacement intervals. The directional surface design is optimized for the Audi S4's braking system, ensuring consistent contact and performance.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive driving or towing\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or humid conditions\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping caused by excessive heat\u003c\/li\u003e\n\u003cli\u003eMinimizes rust and corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking feel and pedal response\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (5 holes, 112mm bolt circle diameter) matches the Audi S4 specifications. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 20mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor distortion.\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 standards for fit, form, and function. The rust-resistant coating and vented design contribute to durability and consistent braking performance.
