Upgrade your WRX or STI with a PERRIN Adjustable Front Swaybar for improved handling and performance. This simple suspension modification reduces body roll, improves cornering, and allows fine-tuning of your car’s handling to match your driving style.

Handling

The PERRIN Front Swaybar reduces body roll and increases cornering performance. With less body roll, tire contact is maximized through turns, resulting in improved grip, more predictable handling, and a more responsive driving experience.

---

Adjustability

Multiple endlink mounting holes let you adjust the swaybar’s stiffness to suit your setup. Whether for daily driving or aggressive track use, the adjustable nature of this bar allows tailored performance to meet your preferences.

---

Bushings

Included with every swaybar are polyurethane bushings, specially designed for better durability and response than OEM rubber bushings. These bushings also feature carved grease-retention pockets to reduce maintenance frequency.

---

Centering Rings

Centering rings help ensure your swaybar stays perfectly aligned during heavy cornering loads, preventing unwanted lateral movement and maintaining consistent performance.

Explain Like I’m 5

A swaybar helps your car stay flat when turning, so it doesn’t lean too much to one side. This makes the car easier to control and more fun to drive.
