The PERRIN 25mm sway bar bushing is specified for WRX and STI applications to provide a firmer mounting point for a 25mm anti-roll bar. Replacing worn OEM bushings, this bushing reduces deflection to restore sharper steering response and reduce chassis roll during cornering. It installs as a direct replacement using factory brackets and hardware to improve handling feel without altering bar geometry.
