Whiteline 08+ Subaru WRX Hatch / 08-09 Subaru STi Rear 20mm Swaybar-heavy duty

This is a Whiteline 20mm heavy duty rear sway bar, part number BSR49. It's designed to fit a range of Subaru vehicles, including models like the 2008-2018 Forester, 2008-2017 Impreza, and 2015-2021 WRX STI. Sway bars are a really effective way to reduce body roll, which is that leaning sensation your car has when you take a corner. By keeping the body flatter, this sway bar helps spread the cornering forces more evenly across your tires. This means you get more grip, which translates to better handling and a more confident feel behind the wheel, without making the ride harsher.

Whiteline builds these sway bars with a tough, protective powder coating to resist corrosion and keep them looking good for a long time, even in rough conditions. The sway bar itself is a solid 20mm diameter, and it features forged ends for maximum strength where the links attach. Inside the mounts, they use a special synthetic elastomer that's resistant to oil and weathering, ensuring it performs well over time. Plus, they include DIY lateral locks to prevent the bar from shifting sideways during hard cornering, and the kit comes with an installation guide to help you get it fitted up.
