With ultra-low compliance joints, this lateral link set significantly improves rear alignment control, handling response, and feedback. There will also be a slight increase in noise and vibration.

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.

$999 SHIPPED SPECIAL INTRODUCTORY PRICE!!

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.

Brake Packages for the WRX

Gruppe-S finally carrys Motul Fluid! People have been asking for some cheap effective brake combos for their WRXs for quite some time now. This is the most cost effective way to improve your brakes.

Porterfield R4S Pads + Goodridge SS Lines + Motul RBF600 Fluid

*The Goodridge Stainless Steel Brake Lines will improve your pedal feel and stop unwanted line flex at high temp.
*The Porterfield R4S Carbon Kevlar Brake Pads have a superior coefficient of friction compared to the stock pads and have excellent fade characteristics. They'll take 20 minutes of weekend track time for beginner to intermediate drivers with no ill effects
*2 Pints of Motul RBF600 Brake Fluid are more than enough to flush your entire brake system. This is some of the best brake fluid out there (DOT4) and is track worthy stuff.





All 4 Corners for 02 WRX - $299 Shipped
All 4 Corners for 03+ WRX - $319 Shipped

New Product!:

Cusco Master Cylinder Brace - 02+ Impreza - $79 Shipped!
Using Cusco’s Brake Cylinder Stopper, the unwanted flex of the brake master cylinder is prevented when the brakes are applied. Flex in the master cylinder manifests itself in inconsistant pedal feel, especially under hard use. This is an excellent modification for road racing.
