PERRIN 15-21 Subaru WRX STI Front Sway Bar - 26mm

The Perrin 26mm front sway bar is a solid option for your 2015-2021 Subaru WRX STI, especially if you're looking to dial in your car's cornering behavior. This bar is constructed from strong, solid steel and features a 26mm diameter, which is larger than the stock unit. This increased diameter helps reduce body roll during turns, giving you a more planted feel when you're pushing the car through corners.

Perrin builds these sway bars with adjustability in mind. You can choose from multiple mounting points on the bar's end links, allowing you to fine-tune the stiffness to match your driving style or track conditions. This adjustability is key for balancing understeer and oversteer, making it a popular choice for enthusiasts looking to improve their car's responsiveness. The bar fits right into the factory mounting locations, simplifying the installation process.

When installing, you'll want to ensure you have access to the end link adjustment points. Properly setting the sway bar tension can make a notable difference in how your car handles transitions. This sway bar is a well-built component that can significantly change the feel of your STI's suspension.
