The drilled and slotted surface pattern helps reduce brake fade by allowing gases and debris to escape, while the vented rotor design improves airflow to maintain optimal operating temperatures. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life under various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to improve heat dissipation during braking, which helps maintain consistent brake performance. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when replacement is necessary to ensure safety. The rotor measures 280 mm in outside diameter and 44.2 mm in overall height, fitting precisely on compatible Fiat 124 Spider and Mazda MX-5 Miata vehicles. The rotor surface is both drilled and slotted in a directional pattern, which aids in removing brake dust and water, improving braking response in various conditions.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive or prolonged braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet conditions\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust buildup for cleaner rotor surface\u003c\/li\u003e\n\u003cli\u003eProvides corrosion resistance to extend rotor lifespan\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 pattern oriented correctly according to the vehicle’s rotation direction. Verify that the rotor thickness is above the discard thickness of 20 mm before installation. Use the 4 bolt holes with a 100 mm bolt circle diameter to secure the rotor properly. It is recommended to inspect brake pads and hardware during installation to maintain overall braking system integrity.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-80074L rotor with rust-resistant coatings and precise machining to meet OEM specifications for Fiat 124 Spider and Mazda MX-5 Miata models.
