Whiteline Front Sway Bar 26mm Adjustable - 2015-2021 Subaru STI

Increasing the thickness of the front sway bar can help reduce understeer which will drastically improve the drivability of your 2015 STI. Picture is only for reference. Take control of your suspension setup and body roll with sway bars from Whiteline. Bigger sway bar = more grip = better handling = outright performance - it's the best dollar for dollar handling improvement you can make to your vehicle. This Whiteline adjustable sway bar allows its rate to be altered by increasing or reducing the length of the lever arms. This permits the roll stiffness to be tuned for different situations without replacing the entire bar. The stiffer the bar, the more force required to move the left and right wheels relative to each other. This increases the amount of force required to make the body roll. This is a solid 2 point adjustable sway bar. SubiSpeed Video (rear sway)
