This design aids in gas and dust evacuation while maintaining consistent braking performance. The black zinc coating on the rotor hat enhances rust resistance, extending rotor life in demanding conditions. This product line is tailored for drivers seeking reliable, vented rotors with directional braking surfaces for specific vehicle fitments like the BMW X3 and X4.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to improve heat dissipation during braking, helping to prevent brake fade. The rotor’s surface is both drilled and slotted, which assists in removing brake dust and gases generated under heavy braking. The directional surface design ensures optimal contact with brake pads for consistent stopping power. The rotor has a nominal thickness of 20 mm and a discard thickness of 18.4 mm, indicating when replacement is necessary. The zinc black finish on the hat provides corrosion resistance, important for maintaining structural integrity over time. The rotor features five bolt holes with a diameter of 16.6 mm and a bolt circle diameter of 120 mm, matching the BMW X3 and X4 specifications.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on BMW X3 and X4\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake pad glazing and uneven wear through slotted and drilled design\u003c\/li\u003e\n\u003cli\u003eResists rust and corrosion for longer service life in wet or salty environments\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance with directional surface design\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 18.4 mm before installation. Clean the hub surface and mounting area to prevent rotor runout. Use proper torque specifications for the five 16.6 mm bolt holes arranged on a 120 mm bolt circle diameter. Verify compatibility with BMW X3 and X4 models before installation. 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 the 633-31152L rotor to meet OEM specifications for fit and function.
