Upgrade your IS300’s handling balance with the FIGS Engineering rear sway bar, designed specifically for the 2001–2005 Lexus IS300. This bar replaces the undersized factory 14 mm rear sway bar with a significantly stiffer 18 mm design to reduce understeer and improve overall chassis balance.

By increasing rear roll stiffness, the FIGS Engineering rear sway bar helps the IS300 rotate more predictably through corners, improving mid-corner grip and exit stability without compromising street drivability when properly adjusted.
