The directional surface features both drilled holes and slots, which aid in removing brake dust, gases, and water from the contact area, improving braking consistency under various conditions. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a clear maintenance threshold for safety. The rotor’s hat is finished with a zinc black coating, providing enhanced resistance to rust and corrosion, which is critical for longevity in diverse driving environments.\u003c\/p\u003e\u003ch2\u003eAbout the DFC 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 that balance performance and durability. This product line features rotors with drilled and slotted surfaces designed to improve braking efficiency and heat management. The black zinc coating on the rotor hat adds a layer of protection against corrosion, making these rotors suitable for drivers seeking reliable stopping power with extended service life on their BMW X5.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW X5 models\u003c\/li\u003e\n\u003cli\u003eImproves brake cooling to reduce fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent brake pad contact by removing debris and gases\u003c\/li\u003e\n\u003cli\u003ePrevents rust buildup on rotor hats for longer component life\u003c\/li\u003e\n\u003cli\u003eSupports directional braking performance for enhanced vehicle control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on the correct side of the vehicle to maintain the directional surface orientation. Verify that the bolt hole pattern (5 holes, 16.6 mm diameter, 120 mm bolt circle) matches the vehicle hub. Measure rotor thickness before installation and replace if below the discard thickness of 18.4 mm. Proper torque specifications should be followed when securing the rotor to avoid warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 633-31138L rotor to meet OEM standards for fitment and performance on BMW X5 vehicles.
