PERRIN’s front swaybar for the 2015–2021 Subaru STI is a performance suspension bar engineered to reduce body roll and sharpen cornering response during spirited street or track driving. It replaces the stock component with a stiffer, adjustable unit for improved vehicle balance and handling feel.

• Stiffer 26 mm diameter bar with two mounting hole options for tuning handling characteristics compared to the OEM 24 mm bar
• Adjustability lets drivers fine-tune roll stiffness to suit street or track use
• Custom polyurethane bushings paired with supplied grease packet for a precise, responsive turn-in
• Includes swaybar unit, bushings, grease packet, PERRIN front license plate frame, warranty, and installation instructions
• Designed specifically for 2015–2021 Subaru WRX STI front suspension applications
• Estimated DIY install time is about 60 minutes with basic tools

This front swaybar is a direct-replacement suspension upgrade that reduces lateral body movement in corners for a more controlled, balanced feel while letting you dial in handling bias via multiple endlink positions.
