This design helps maintain consistent brake pad contact and reduces brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life, while the vented rotor design aids in heat dissipation for improved performance on Mazda 3 and Mazda 3 Sport vehicles.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow airflow between the rotor surfaces, which helps reduce heat buildup during braking. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, indicating when replacement is necessary. The rotor surface is both drilled and slotted, providing a directional braking surface that enhances pad bite and helps remove debris and moisture. The rotor’s hat is coated with a rust-resistant zinc silver finish, while the disc surface has a plain finish. It features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 72 mm, matching the Mazda 3 and 3 Sport specifications.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Mazda 3 and Mazda 3 Sport\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or humid conditions by evacuating water\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eMaintains consistent brake pad contact through directional slotted and drilled design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (23 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface and hub mounting area to prevent uneven wear\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for the 5 lug bolts (bolt circle diameter 114.3 mm)\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with Mazda 3 and Mazda 3 Sport models before installation\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary to optimize performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-80041L rotor to meet OEM specifications for Mazda 3 and Mazda 3 Sport vehicles.
