This design helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for solid rotors with directional surfaces, suitable for vehicles requiring precise fitment and reliable braking under varied conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis rotor features a solid disc construction with a nominal thickness of 11.04 mm and a discard thickness of 9 mm, ensuring safe replacement intervals. The rotor's overall height and hat height are both 50.5 mm, with a center hole diameter of 70.6 mm. The 5 bolt holes and stud\/lug holes each measure 16.3 mm in diameter, arranged on a 118 mm bolt circle diameter, matching the wheel hub specifications of compatible vehicles.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBuick Alero, Century, Regal\u003c\/li\u003e\n\u003cli\u003eChevrolet Impala, Monte Carlo\u003c\/li\u003e\n\u003cli\u003eOldsmobile Intrigue\u003c\/li\u003e\n\u003cli\u003ePontiac Grand Am, Grand Prix\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis rotor is designed to address common braking issues such as brake fade, uneven rotor wear, and reduced stopping power caused by heat buildup or surface contamination.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during extended braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent warping\u003c\/li\u003e\n\u003cli\u003eEnhances braking response with directional slotted and drilled surface\u003c\/li\u003e\n\u003cli\u003eResists rust and corrosion for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent pad contact for smoother stops\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 9 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the vehicle’s hub using the 118 mm bolt circle diameter and 5-lug pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction rotors undergo rigorous quality control to meet OEM standards.
