Detailed Description

DuraGo BR31311 is engineered as a front brake rotor for 2002-2006 Acura RSX, 2004-2011 Honda Civic, and 2011-2015 Honda CR-Z front brake service. Its vented design helps manage heat during repeated stops, while the non-directional surface supports straightforward resurfacing and installation. The rotor’s dimensions, including the 261.5 mm outside diameter, 64.1 mm center hole, and 114.3 mm bolt circle, align with the specified OE-style fitment for these vehicles. This part cross-references Raybestos Brakes 980059 for the same application.

Common Repair Uses

• Front brake pulsation caused by rotor wear or thickness variation
• Brake noise related to worn or uneven rotor surfaces
• Reduced stopping consistency from heat-affected rotors
• Service replacement for rusted or scored front rotors
• Brake maintenance on Honda Civic, Honda CR-Z, and Acura RSX front axles

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. Clean the hub mounting surface thoroughly to help prevent runout concerns, and inspect pads, calipers, and hardware condition during brake service. Because this rotor is non-directional and vented, it can be installed without left- or right-specific orientation.

Quality Assurance

DuraGo has over 45 years of aftermarket manufacturing experience, and its brake drum and rotor program is produced in ISO-certified factories focused on fit, form, and function. The BR31311 reflects that manufacturing approach for service on select Honda and Acura front brake applications.
