The rotor’s surface combines drilled holes and slots, which help evacuate gases, dust, and water, contributing to better brake pad contact and reduced brake fade. The directional surface pattern ensures the rotor is installed correctly for optimal performance.\u003c\/p\u003e\u003cp\u003eThe rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life. The rotor features five bolt holes with a 114.3 mm bolt circle diameter, matching the stud\/lug hole pattern of INFINITI J30 and Q45 models. The center hole diameter is 68 mm, and the stud\/lug hole diameter is 12.7 mm, ensuring precise fitment.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on delivering rotors with enhanced heat dissipation and improved braking response. The drilled and slotted design is intended to reduce brake fade and maintain consistent performance in various driving conditions. The silver zinc coating on the hat offers rust resistance, making these rotors suitable for vehicles exposed to moisture and road salt.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped rotors on INFINITI J30 and Q45\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust resistant coating\u003c\/li\u003e\n\u003cli\u003eRestores proper brake rotor thickness for safe stopping power\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify that the rotor thickness is above the discard thickness of 26 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting.
