Ask any racer, any REAL racer, and they will tell you that the best bang for the buck handling mod you can give your Evo X is a high-performance sway bar. So with over 40 years of automotive sway bar and suspension design, you know you can trust your Evo 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 Evo X. 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 Evo X 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 sway bar, grip can be biased towards the front end of the car, effectively eliminating the factory understeer and creating oversteer. Whiteline sway bars for the Evolution X are adjustable, allowing you to dial in your desired front or rear stiffness and tune in understeer or oversteer as you please. Whether you are building a time attack monster or just sprucing up your daily driver, you can be sure there is a Whiteline sway bar 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 sway bar kit for your Evo X.
