Perrin 08-14 WRX / 09-14 STI / 13-20 & 2022 BRZ / 2022 Toyota GR86 16mm Rear Swaybar

Sway bars are one of the most important upgrades you can make to a Subaru’s suspension system, and Perrin’s sway bars are engineered to do more than just reduce body roll—they fundamentally change how the car responds to aggressive cornering, weight transfer, and driver inputs.

Constructed from precision mandrel-bent solid or tubular steel (depending on application), Perrin sway bars are designed with both daily driving comfort and high-performance cornering in mind. By increasing the stiffness between the left and right sides of the suspension, these bars help keep the car flatter through turns, resulting in sharper turn-in, better mid-corner grip, and more confidence at the limit.

Each bar is powder-coated for corrosion resistance and longevity, and includes heavy-duty polyurethane bushings to reduce flex and eliminate unwanted movement. Many applications also include multiple endlink mounting positions, allowing the driver to fine-tune handling balance—whether you’re dialing in more oversteer for autocross or more neutral handling for daily use.

• Reduces body roll for flatter, more predictable cornering
• Mandrel-bent steel construction ensures consistent performance and long-term durability
• Multi-position adjustability allows fine-tuning of handling balance
• Includes upgraded polyurethane bushings for better response and reduced flex
• Corrosion-resistant powder coat finish ensures years of reliable use

Whether you’re building a canyon carver, a track weapon, or simply want more composure on spirited drives, Perrin sway bars are an essential foundation for a more capable and responsive suspension setup.
