This configuration helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver hat finish offers corrosion resistance, extending the rotor's service life, making it suitable for Acura RL vehicles that demand consistent braking under various driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring safe replacement intervals. The rotor's 319 mm outside diameter and 50 mm height accommodate the specific fitment requirements of Acura RL models. The vented design promotes airflow to reduce heat buildup during braking. The rotor surface is both drilled and slotted with a directional pattern, which aids in water and gas evacuation, improving brake pad contact and performance. The zinc silver coating on the hat area provides rust resistance, helping maintain structural integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation for consistent stopping power\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor surface glazing and brake pad deposits\u003c\/li\u003e\n\u003cli\u003eResists rust and corrosion for longer rotor life\u003c\/li\u003e\n\u003cli\u003eCompatible with Acura RL models requiring vented, drilled, and slotted rotors\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 26 mm before installation. The rotor features 5 bolt holes with a 14.7 mm diameter and a 120 mm bolt circle diameter, matching the Acura RL specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.
