The black zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented vehicles like the Subaru WRX and WRX STI, offering reliable braking under aggressive driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The directional slotted and drilled surface improves water and debris evacuation, maintaining consistent braking performance in various conditions. The rotor measures 326 mm in outside diameter and 63.4 mm in height, fitting precisely on Subaru WRX and WRX STI models. The zinc black hat finish provides rust resistance, protecting the rotor’s core structure.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance for Subaru WRX and WRX STI vehicles\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during high-performance or spirited driving\u003c\/li\u003e\n\u003cli\u003eHelps prevent rotor warping caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eEnhances water and debris evacuation for consistent braking in wet conditions\u003c\/li\u003e\n\u003cli\u003eProtects against rust and corrosion with zinc black coating\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 18 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug, 114.3 mm bolt circle diameter pattern on your Subaru WRX or WRX STI. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the rotation arrow pointing in the correct direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 633-13042L rotor to meet strict quality standards for durability and performance.
