The cross-drilled holes and slots help evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent pedal feel. This product line is suitable for drivers seeking reliable braking upgrades for their Acura MDX or TLX without altering the original braking system architecture.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis vented rotor features a floating disc mounting design that allows for slight movement between the rotor and hat, reducing stress and improving heat dissipation. The rotor’s coated hat finish protects against corrosion, extending service life. With a 320 mm outside diameter and a nominal thickness of 28 mm, these rotors meet OEM fitment requirements. The 5-lug hole pattern with a 114.2 mm bolt circle diameter ensures proper fitment on compatible Acura MDX and TLX models. The rotor includes 44 straight vanes for efficient airflow and cooling.\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 to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eEnhances wet weather braking performance by channeling water away\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust buildup on rotor surface\u003c\/li\u003e\n\u003cli\u003eMaintains consistent brake pedal feel under heavy use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure compatibility with Acura MDX and TLX models before installation.
