This product line features cross-drilled rotors designed to improve braking efficiency by enhancing heat dissipation and reducing brake fade. The rotors are vented and coated to provide durability and corrosion resistance, making them suitable for performance-oriented BMW vehicles such as the 330Ci, 330i, and Z4.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor has an outside diameter of 325 mm (12.795 inches) and an overall height of 52.8 mm (2.079 inches). The nominal thickness is 25 mm (0.984 inches), with a discard thickness of 23.4 mm (0.921 inches), ensuring safe replacement intervals. The rotor features a 5-lug bolt hole pattern with a 120 mm (4.724 inches) bolt circle diameter and a center hole diameter of 79 mm (3.110 inches). The hat is coated to resist corrosion, and the rotor uses a floating disc mounting system to maintain proper alignment during operation. This rotor does not include ABS tone rings or bearings.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on BMW 330Ci, 330i, and Z4 models\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat during aggressive driving\u003c\/li\u003e\n\u003cli\u003eImproves braking performance and pedal feel with cross-drilled design\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion-related rotor damage with coated hat finish\u003c\/li\u003e\n\u003cli\u003eEnsures proper rotor alignment and longevity with floating disc mounting\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 23.4 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the 5-lug bolt pattern with a 120 mm bolt circle diameter. Since this rotor does not include bearings or ABS tone rings, reuse existing components if applicable. It is recommended to replace brake pads simultaneously for optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric Premium OE Style Cross-Drilled Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
