The rotor measures 300 mm in outside diameter and features a nominal thickness of 22 mm, with a discard thickness of 20.4 mm to ensure safe replacement intervals. Its directional surface is both drilled and slotted, which helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor’s hat is finished in zinc black, providing corrosion resistance along with a rust-resistant coating on the entire rotor surface. The 5-bolt hole pattern with a 14.6 mm diameter and a 120 mm bolt circle diameter ensures precise fitment and secure mounting.\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 on a directional surface to optimize braking performance and rotor longevity. This product line is designed to provide consistent braking under demanding conditions by enhancing heat dissipation and maintaining pad contact. The zinc black hat finish and rust-resistant coating contribute to durability and corrosion protection, making it suitable for BMW vehicles requiring reliable replacement rotors.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 3 Series and Z models\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eHelps prevent brake pad glazing by maintaining a clean rotor surface\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eRestores braking performance and pedal feel for safer driving\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (20.4 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface with brake cleaner to remove any protective oils\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications using a star pattern\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and replace if worn to ensure optimal rotor performance\u003c\/li\u003e\n\u003cli\u003eCheck for proper fitment on BMW 323i, 325Ci, 325i, 325xi, 328Ci, 328i, Z3, and Z4 models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Black to meet or exceed OEM specifications for fit, form, and function.
