The drilled and slotted surface improves water and debris evacuation, enhancing wet weather braking performance. The rotor’s directional surface ensures proper alignment for optimal braking response. With a nominal thickness of 42 mm and a discard thickness of 40.4 mm, it maintains structural integrity and safety throughout its service life.\u003c\/p\u003e\u003cp\u003eThe rotor’s hat is finished in zinc silver, providing corrosion resistance, while the entire rotor is coated with a rust-resistant layer to extend durability. It includes eight bolt holes with a 13 mm diameter and a bolt circle diameter of 145 mm, suitable for vehicles requiring this specific fitment. The overall diameter of 345 mm and height of 116.7 mm make it compatible with a range of applications requiring these dimensions.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This product line is designed to provide consistent braking performance under demanding conditions, with vented rotors that help manage heat buildup. The silver zinc finish adds protection against rust, making these rotors suitable for vehicles exposed to varying weather conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade caused by excessive heat during heavy braking\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or debris-prone environments\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on the rotor surface for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity with precise thickness specifications\u003c\/li\u003e\n\u003cli\u003eEnsures proper fitment with 8-bolt, 145 mm bolt circle diameter vehicles\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 oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the vehicle’s hub using the 13 mm bolt hole diameter and 145 mm bolt circle diameter. Check rotor thickness before installation to confirm it is above the discard thickness of 40.4 mm.
