Ask any racer, any REAL racer, and they will tell you that the best bang for the buck handling mod you can give your Mini Cooper S is a high-performance sway bar. With over 40 years of automotive sway bar and suspension design, you know you can trust your Cooper S to the experts at Whiteline. 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 MCS. Increasing the diameter of your rear sway bar 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 FWD platforms, the Mini Cooper S is designed to be biased towards understeer. By adding a significantly 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 Mini Cooper S are available as adjustable bars allowing you to dial in your desired front or rear stiffness and tune out understeer or oversteer as you please. Whether you are building a cone dodger 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 Mini Cooper S.
