STi Engine Mounts (Pair) - 02+ WRX
$110 shipped !

Excellent for people who drive their car on the track and autocross. While on the track, the engine mounts are subjected to extreme pressure and wear under breaking, acceleration, and turning. These STi mounts are substantially stiffer and more durable than the stock ones meaning that the engine will remain where it is supposed to be during extreme g-loads. Engine mounts should generally be replaced with tranny mounts so that undue stress is not placed on the stock mounts that are not replaced.


STi Transmission Mount - WRX 02+
$79 shipped !

Similar to STi engine mounts but for your tranny.

Combo for Engine/Tranny mount $175 shipped !


STi Pitch Stop Mount - 02+ WRX
$55 shipped !

The STi pitch stop mount keeps your motor from diving and squatting under hard braking and acceleration. Like the STi engine and tranny mounts, this is substantially stiffer and more durable than the stock one.

Helix STi Rear Endlinks (Full Pillowball) - 04+ STi
$99 shipped !

These make 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.


Cusco 22mm Rear (3-way Adjustable) Sway Bar- 04+ STI
$155 shipped !

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 promote rotation at the rear of the car and thus oversteer while also allowing the car to turn in more quickly.

Combo price for Helix STi Rear Endlinks + Cusco 22mm Rear Sway for STi
$240 shipped !


STi Replica - Front - 02+ WRX $75 shipped
STi Replica - Rear - 02+ WRX $60 shipped
$115 for both shipped

Suspension upgrades such as high performance springs, shocks and tires can add additional stress to the chassis resulting in additional chassis flex. These STi Replica Strutbars improve chassis rigidity and reduce this flex. By using a monocoque aluminum tube shaft, high strength and rigidity are obtained without unnecessary weight gain.

Goodridge Stainless Lines - Front+Rear - 02+ WRX
$129 shipped !

Under extreme conditions, brake fluid heats up which often causes your stock rubber lines to expand. This translates into a spongy feeling brake pedal. One of the easiest way to improve your brake feel is to use stainless steel braided lines which aren't as succeptable to flex and expansion.

Buddy Club Racing Spec Coilovers - WRX 02+
$1175 Shipped ! ! Reg. price $1500 shipped



The Buddy Club Racing Spec Damper system was developed based on the data collected from both actual racecars and the high-performance streetcar. Depending on different applications, adequate spring rates, damping force adjustment, and enough damping stroke were all put into consideration to create the one of the best available and balanced suspension systems for the drifting and circuit enthusiasts alike.

Because strut type suspension absorbs the shock directly from the road, it requires a high strength design. Buddy Club utilizes the inverted shock design for its high durability. The inverted shock tubes are manufactured with corrosion free chrome plated steel.

15 Way Compression / Rebound Adjustment
15 different settings are possible with just a simple click on a ****. Inverted shocks have the adjustment **** on the top of the shaft. The others have the ***** at the bottom of the shell case. The basic compression (softest setting) offers excellent comfort for daily street use of the suspension kit. About 4kg/mm spring rate increase is expected with the damping force set to all the stiffest setting.

Pillow Ball Upper Mounts
Steering response will be dramatically improved by adding upper pillow ball mounts instead of the factory rubber bushing. Aluminum upper mounts will let you adjust the camber on several strut type suspension kits.

Original Springs
High quality original springs are used on all of our suspension kits. A special coating gives extra protection against any corrosion caused by the everyday driving.

Bracket Adjustable
Buddy Club has eliminated the need for helper springs by using the adjustable bracket system. A Super low ride-height is possible without having any free play of the springs. One complete turn of the adjusting bracket will lower the ride-height approximately 2mm. The shell case finish is an off black coating to prevent corrosion and offer a high quality feel.

Mono Tube Design Shell Case
All Racing Spec Damper uses the mono tube design shell case instead of an inferior ordinary cartridge type. Strut type application uses a 36mm piston and wishbone type uses an extremely large 46mm piston for greater control of the damping force.

Spring Seat, Lock Seat
This aluminum material spring seat / lock seat will let you adjust the height 2mm for every one full complete turn. By using the pre-loadable adjusting bracket it is now possible to change the spring pre-load without the vehicle height.

Spring Rating:
Front: 8 kg/mm
Rear: 6 kg/mm
