Cusco 22mm Front Sway Bar - 04+ STi
-Often described as the single most aggressive suspension modification for your Impreza, the addition of stiffer swaybars properly distributes cornering forces by reducing lateral sway applying increased cornering force on the outside wheel and will ultimately increase vehicle turning characteristics. The rear sway bar will increase oversteer and allow the car to turn tighter, while the front sway bar will have the tendency to increase understeer.

Helix Rear Endlinks - 02+ WRX
-Helix Solid Endlinks are CNC machined from high strength aluminum. This makes an excellent replacement for your factory plastic endlinks which tend to twist and bend upon corner-loading. The addition of Helix Solid Endlinks significantly increases cornering response and tightness, regardless of the use of an aftermarket sway bar or not. The use of spherical bearings allows for a much wider range of angular movement and eliminates the squeaking and creaking associated with the deterioration of rubber or urethane bushings. The spherical bearings are teflon coated to prevent dirt and debris from fouling movement.

Guys, these coilovers have actually been available for several months. But they were not released until we tested these coilovers for ourselves. We have not only ran these coilovers in our street cars (for longevitiy and durability testing), we have heaped tons of abuse on these coilovers at various tracks around California, including Thunderhill, Buttonwillow, etc. We feel that these coilovers are simply the best bang for the buck coilovers available on the market. :)
