The PERRIN rear sway bar bushing is a direct-fit replacement sized for a 25mm rear anti-roll bar on 2008 Subaru STI/WRX models. It restores the bushing interface between the bar and chassis to reduce play and help maintain proper roll control. Offered as a simple service item, it supports cleaner suspension response when worn factory bushings are replaced with the correct 25mm fitment.
