Whiteline 27mm Front Adjustable Swaybar - 04-07 STI. So with over 40 years of automotive swaybar and suspension design, you know you can trust your STI to the experts at Whiteline. As a brand, Whiteline adheres to a strict 'no bling' policy when developing their products, meaning you won't find a wide array of colors or useless cosmetics, just great quality parts and guaranteed performance for your STI.
Increasing the diameter of your sway bars will have two main effects. They will modify handling balance in terms of steering bias (understeer or oversteer), and they will increase roll resistance. Like many AWD platforms, the stock STI is designed to be biased towards understeer, meaning that the installation of a larger rear sway bar will eliminate the rear end grip bias and provide a more neutral handling feel. By adding a significantly a stiffer rear swaybar, grip can be biased towards the front end of the car, effectively eliminating the factory understeer and creating oversteer.
Whiteline sway bars for the STI are available as either a fixed or adjustable design, allowing you to dial in your desired front or rear stiffness. Whether you are building a time attack monster or just sprucing up your daily driver, you can be sure there is a Whiteline swaybar to suit your needs. All Whiteline sway bars are constructed from solid steel and come in "Silver Sparkle II" metallic powder coat color. Replacement polyurethane bushings, installation grease and instructions are included in each Whiteline swaybar kit for your STI.
