Restore Precise Front Sway Bar Control
The factory front sway bar mount bushings on the WRX, Impreza, and STI wear out and allow the bar to shift under load, softening handling response. This Whiteline W0405-18 front sway bar mount bushing kit uses a synthetic elastomer compound with a PTFE inner lining to lock the bar in place without requiring grease maintenance.
