The surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent braking performance. The directional brake surface ensures proper rotation alignment for optimal efficiency. The rotor’s nominal thickness is 19.9 mm, with a discard thickness of 18.4 mm, indicating when replacement is necessary to maintain safety and performance. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance along with a rust resistant coating applied to the entire rotor surface. The rotor measures 320 mm in outside diameter and 86.1 mm in height, with a center hole diameter of 75 mm. It features 5 bolt holes with a diameter of 14.8 mm and a bolt circle diameter of 120 mm, matching the specifications required for the listed BMW models.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Geoperformance Rotor - Drilled and Slotted Line\u003c\/h2\u003e\u003cp\u003eThe DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction is designed to offer enhanced braking performance through advanced rotor surface technology. The drilled and slotted design improves heat dissipation and debris removal, which is critical for maintaining brake efficiency in both everyday driving and more demanding conditions. This line is engineered to meet the precise fitment and performance requirements of specific vehicle models, including various BMW xDrive and xi variants.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking response and reduces brake fade during high-stress driving\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eReduces brake dust accumulation on pads and wheels\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance in wet or humid conditions\u003c\/li\u003e\n\u003cli\u003eExtends rotor lifespan with rust resistant coating and durable finish\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 direction. Verify that the bolt hole pattern (5 holes, 14.8 mm diameter, 120 mm bolt circle) matches the vehicle hub. Check rotor thickness before installation; replace if below the discard thickness of 18.4 mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor damage or uneven wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 830-31075L rotor to meet strict quality standards, including rust resistant coatings and precise machining tolerances.
