Its vented design improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The rotor’s surface is both drilled and slotted, allowing for efficient removal of brake dust, gases, and water, which can improve brake pad contact and reduce fade under demanding conditions.\u003c\/p\u003e\u003cp\u003eConstructed with a plain disc finish and a zinc black coated hat, this rotor offers corrosion resistance to extend service life. The rotor’s dimensions, including a 320 mm outside diameter and 52.2 mm overall height, are engineered to match factory specifications for a direct replacement. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment on compatible Audi vehicles.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Drilled and Slotted - Black Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish on the hat. This product line is designed to provide enhanced heat dissipation and improved braking performance while maintaining durability and resistance to rust, making it suitable for both daily driving and more demanding conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Audi A4, A4 Quattro, A5, A5 Quattro, and Q5\u003c\/li\u003e\n\u003cli\u003eImproves brake cooling to reduce fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake pad glazing and uneven wear\u003c\/li\u003e\n\u003cli\u003eReduces brake dust accumulation for cleaner braking surfaces\u003c\/li\u003e\n\u003cli\u003eAddresses corrosion issues 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 28 mm before installation. Clean the rotor surface to remove any protective coating or contaminants prior to mounting. Verify the 5-bolt hole pattern and 112 mm bolt circle diameter match your vehicle’s hub. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function.
