PERRIN 08-21 WRX/STI & 13-26 BRZ/FR-S/86/GR86 Rear Sway Bar - 18mm

This is the Perrin 18mm adjustable rear sway bar, designed to fit 2008-2021 Subaru WRX and STI models, as well as 2013-2026 Scion FR-S, Subaru BRZ, Toyota 86, and GR86. Adding a larger rear sway bar like this one helps reduce body roll during cornering, making your car feel more stable and responsive when you're turning.

Perrin makes this sway bar from solid steel for strength, and it's adjustable, meaning you can fine-tune how much it affects your car's handling. You can set it to a stiffer setting for flatter cornering or a softer setting if you prefer a bit more give. This adjustability lets you dial in the feel you want for spirited driving or track use.
