Detailed Product Description

This Raybestos R-Line rotor (part number 982433R) is a vented, conventional disc brake rotor designed specifically for Subaru WRX and WRX STI models. The vented design enhances cooling by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during aggressive driving or heavy braking conditions. The rotor features a smooth surface type, ensuring even brake pad wear and consistent braking performance.

With an outside diameter of 326 mm and a nominal thickness of 20 mm, this rotor meets OEM specifications for fit and function. The discard thickness of 18 mm indicates the minimum safe thickness before replacement is necessary, helping maintain braking safety. The rotor mounts with five bolts on a 114.3 mm bolt circle diameter, matching Subaru factory specifications for secure installation.
