Product Fitment:

2008-2016 Subaru Impreza Non Turbo

The Whiteline 22mm 3-point adjustable rear sway bar is designed to significantly improve chassis balance and cornering performance on Subaru Impreza platforms (GE/GH/GJ/GP, 2008–2016). By reducing body roll, this upgrade helps distribute lateral load more evenly across the tires, increasing overall grip and improving handling precision during spirited driving or track use.

This is one of the most effective suspension upgrades for improving turn-in response and reducing understeer without sacrificing everyday ride comfort.

Key Features & Benefits

• 22mm solid spring steel construction
• 3-point adjustability (soft / medium / hard settings)
• Reduces body roll during cornering
• Improves tire contact patch consistency
• Enhances steering response and vehicle balance
• Helps reduce understeer in AWD Subaru platforms
• Does not significantly impact ride comfort
• Ideal for street, autocross, and track use

Adjustability Settings

The bar’s effective stiffness changes depending on mounting position:

• Soft (21mm effective): Comfort-focused, mild grip increase
• Medium (22mm effective): Balanced daily performance setup

Each step increases torsional resistance, allowing drivers to fine-tune rear grip and rotation behavior depending on driving style and conditions.
