Whiteline 08+ Subaru WRX Hatch / 08-09 Subaru STi Rear 24mm Swaybar-XX heavy duty Blade adjustable

When you're looking to firm up your Subaru's handling, this Whiteline rear sway bar kit is a solid option. What you get in the box is everything you need to get started: a 24mm heavy-duty adjustable rear sway bar, two bushings, two braces, two lateral locks, two bolts, and four washers. This kit is designed to reduce body roll, which means your tires will have a stronger grip on the road when you're taking corners. That improved grip translates directly into better handling and a more confident feel behind the wheel, and it can even help your tires wear more evenly over time.

This particular sway bar is a 24mm, 3-point adjustable unit. The larger 24mm diameter makes it stiffer than a stock sway bar, which is key to cutting down on body roll. The adjustability lets you fine-tune how the car handles to match your driving style or the conditions. Whiteline uses advanced synthetic elastomer bushings that resist oil, grease, and weathering, ensuring they hold up well. The metal components are protected with plating and powder coating to resist corrosion, and the forged ends at the link mounting points add strength.

This sway bar fits a range of Subaru models, including the WRX, STI, Forester, and Outback. Installation is straightforward, often taking about an hour for a DIYer, and it's a direct bolt-on process. It's a popular upgrade because it makes a noticeable difference in how the car corners without negatively impacting ride comfort.
