Progress Tech 13-16 Scion FR-S/13+ Subaru BRZ Rear Sway Bar (17.5mm - Adjustable)

When you're looking to tighten up the handling on your 2013-2020 Subaru BRZ or 2013-2016 Scion FR-S, this rear sway bar from Progress Technology is a solid option. It's designed to replace your factory bar and bushings with a larger diameter, solid alloy steel bar and harder polyurethane bushings. This setup increases the 'roll stiffness' of your car's suspension, which means less body lean when you're cornering. Less lean means your tires stay flatter on the pavement, giving you more grip and better control.

Progress Technology builds these bars in-house using CNC bending equipment for a precise fit. The ends are laser-cut and CNC-machined, then MIG-welded in place. This attention to detail ensures the bar connects properly to your suspension. The bar itself is 17.5mm in diameter and features adjustability, allowing you to fine-tune how much it affects your car's handling balance. This is a popular way to reduce the understeer that many modern cars can exhibit.

This kit includes the 17.5mm adjustable rear sway bar. You'll want to check the manufacturer's instructions for any specific hardware or tools needed for installation, as it replaces the stock components.
