I installed the 22mm Whiteline sway bar on my 2010 Subaru WRX, and the difference in handling is night and day. Installation was relatively easy with basic tools, though having an extra set of hands helps. The biggest improvement is reduced body roll and sharper turn-in response—cornering feels much more planted. Despite the stiffer setup, daily driving comfort remains intact. For WRX owners looking for better handling without sacrificing comfort, this sway bar is a solid upgrade. Highly recommend!
