The rotor’s vented construction allows air to flow between the rotor faces, helping to dissipate heat more effectively during aggressive braking. The drilled and slotted surface pattern is directional, which aids in channeling away brake dust, gases, and water, improving pad bite and reducing brake fade. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring a reliable service life before replacement is necessary.\u003c\/p\u003e\u003cp\u003eThe rotor features a plain disc finish combined with a Geospec silver grey hat finish, providing rust resistance and maintaining structural integrity over time. With 4 bolt holes and a bolt circle diameter of 100 mm, this rotor fits securely on the specified vehicles. The center hole diameter measures 55 mm, and the stud\/lug hole diameter is 13.3 mm, matching factory specifications for proper fitment.\u003c\/p\u003e\u003ch2\u003eDFC Geoperformance Rotor - Drilled and Slotted Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced thermal management and surface design. This product line incorporates vented rotors with directional drilled and slotted surfaces to optimize braking performance under demanding conditions. The rust resistant coatings and precision finishes contribute to durability and consistent operation, making this rotor suitable for performance-oriented vehicles like the Fiat 124 Spider and Mazda MX-5 Miata.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves brake cooling to reduce fade during spirited driving\u003c\/li\u003e\n\u003cli\u003eHelps prevent brake pad glazing by channeling away debris and gases\u003c\/li\u003e\n\u003cli\u003eReduces rust and corrosion on rotor surfaces for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance with vented rotor design\u003c\/li\u003e\n\u003cli\u003eEnsures proper fitment and secure mounting on Fiat 124 Spider and Mazda MX-5 Miata\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Dynamite Friction 830-80074L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the directional drilled and slotted pattern is oriented correctly according to the vehicle’s rotation direction. Check that the rotor thickness is above the discard thickness of 20 mm before installation. Use proper torque specifications for the 4 bolt holes with a 100 mm bolt circle diameter to secure the rotor safely.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 830-80074L rotor to meet or exceed OEM specifications for the Fiat 124 Spider and Mazda MX-5 Miata.
