Description
Whiteline BBF15Z provides front 30mm heavy duty adjustable sway bar for 01-06 BMW M3 (E46).
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

Select a suitable starting position if the bar is adjustable, then evaluate the vehicle’s balance before progressing to a firmer setting.
