Whiteline '08-'14 Subaru WRX STi Heavy Duty Adj Rear 24mm Sway Bar
Rear 24mm Swaybar-XX Heavy Duty Adjustable
As the name suggests their objective is to reduce sway, or body roll, and stabilize a vehicle under lateral (cornering) forces. Formula 1 cars still use sway bars along side the shocks and springs as it is the ONLY suspension component principally designed to control body roll. Unfortunately, many aftermarket spring manufacturers still design their lowered springs too hard, trying to control body roll when it’s the sway bars job.
The fitting of bigger Whiteline Swaybars is still the best dollar for dollar handling improvement you can make.
Whiteline Swaybars are manufactured using the finest grade Australian spring steel. They are powder coated and supplied with high performance Synthetic Elastomer mounting bushes in a DIY kit form, ready to simply bolt on.
*Whiteline Adjustable Sway Bars*
Adjustable sway bars allow their stiffness 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.
