Racing Beat's Mazda 3s Front Sway Bar for the 2010-12 Sedan or 5-Door (2.5L) - Racing Beat-designed sway bars reduce chassis roll during cornering and increases your car's sensitivity to steering inputs, thereby improving maximum cornering power. Substantial engineering effort, select steel alloys, and precise heat-treating processes are combined to produce top performance components. All Racing Beat sway bars are finished with a distinctive, red powder coating that provides a smooth, glossy protective layer. You can be assured of many years of superior handling performance with these proven bars! The diameter of the Racing Beat Mazda 3 front sway bar is 1.125" (28.5mm), as compared to the stock .83" (21mm) front bar and is 3.4 times stiffer than the stock bar. An additional feature of the Mazda 3 front sway bar is a pair of OEM style "stoppers" to prevent the bar from sliding sideways in the bar bushings during heavy cornering effort. Each bar is supplied with Mazda 3-specific replacement urethane bushings, bar clamps, Prothane grease and installation instructions.
