The rotor's surface is both drilled and slotted, which assists in removing brake dust, gases, and water from the contact area, improving brake pad bite and reducing the risk of brake fade. The directional brake surface ensures optimal performance when installed in the correct orientation.\u003c\/p\u003e\u003cp\u003eThe rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, indicating when replacement is necessary to maintain safe braking. The hat section is finished with a zinc black coating, providing rust resistance and extending the rotor's service life. With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor is designed to fit securely on the Audi S4 hub assembly.\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 delivering rotors with enhanced heat management and corrosion resistance. This product line combines drilled holes and slots on the rotor surface to improve braking efficiency and durability, making it suitable for performance-oriented vehicles like the Audi S4. The black zinc finish on the hat area adds an extra layer of protection against rust, which is critical for maintaining rotor integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves brake cooling to reduce fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake dust buildup on rotor surface\u003c\/li\u003e\n\u003cli\u003ePrevents premature rotor corrosion with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eEnsures proper fitment and secure mounting on Audi S4 vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Dynamite Friction 633-73032L rotor on an Audi S4, ensure the directional slotted and drilled surface is oriented correctly according to the vehicle’s rotation direction. Verify that the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Use proper torque specifications for the 5 lug bolts to secure the rotor firmly.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 633-73032L rotor to meet or exceed OEM specifications for fit, form, and function.
