This design helps maintain consistent braking performance under demanding conditions. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life while maintaining a clean appearance.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional drilled and slotted surface improves pad bite and helps prevent brake fade by efficiently removing gases and debris. The rotor has a nominal thickness of 22mm and a discard thickness of 20mm, ensuring safe replacement intervals. The zinc black hat finish and rust-resistant coating protect against corrosion, which is critical for maintaining rotor integrity over time. The rotor features 4 bolt holes with a 100mm bolt circle diameter and a center hole diameter of 55mm, matching the fitment requirements for the specified vehicles.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Fiat 124 Spider and Mazda MX-5 Miata\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during spirited driving or 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 and zinc black hat finish\u003c\/li\u003e\n\u003cli\u003eEnhances brake pad bite and reduces brake noise through slotted and drilled surface design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 20mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the 4-bolt, 100mm bolt circle diameter pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\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.
