Whiteline Front 26mm Adjustable Sway Bar – 15-21 Subaru WRX STI

Whiteline BSF48Z provides front 26mm adjustable sway bar for 15-21 Subaru WRX STI.

How It Works

The sway bar contributes roll stiffness by resisting differences in suspension movement across the axle. Its effect depends on diameter, construction, mounting geometry and effective lever length. A change at one axle can alter understeer/oversteer balance; diameter alone does not establish a percentage increase in stiffness or guarantee more grip.

Installation & Selection
