DNA SERIES - Helix DNA Sport Coilovers are designed to suit the average vehicle enthusiast. Unlike race coilovers which often exhibit harsh ride characteristics, high cost, and sometimes excessive noise, Helix DNA Sport Coilovers are designed primarily for street service with mild track service in mind. Featuring excellent ride characteristics and lower cost, these coilovers are a fine balance of street function and track service. Fully rebuildable and available in multiple spring rates.

- Light aluminum Shock Body
- 16 Pt Dampening / Rebound Adjustable
- Full Upper Pillow Ball Mounts
- Camber Adjustable
- 8kg / 6kg spring rates
$999 SHIPPED :eek: 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. :)

Please contact us for ordering information!

Thanks!

Hey people,

We also have some STi Rear Lateral Links (Full Pillowball) and Trailing Arms in stock. These are fresh of the boat from Japan and usually take 2-3 months to get. We have 1 set for the 02+ WRX and 1 set for the 05 STi. These will make a dramatic difference in the way your car handles by tightening up your rear control arms. This is a particularly good modification for those who track or autocross their car.

The six piece STi rear lateral link set upgrades all 8 link bushings to pillow ball type joints (spherical bearings) sealed against dirt intrusion. Also includes metal (w/ uniball joints) rear swaybar links with adapter brackets. 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. The trailing arms replace the rear front trailing link bushing with pillow ball joints. Completes the set of rear suspension members when combined with one of the lateral link sets.

$849 Shipped for the set for 02+ WRX!

$639 shipped!!!

Cusco!

Cusco V2 Lower Arm Bar - 02+ WRX / 04+ STi
-The purpose of the Cusco lower arm bar is to reduce alinement flexing and improve body rigidity. The lateral arm improves body and rigidity by connecting at the lower arm points. Thus preventing body flex and therefore dramatically improving steering, throttle response and traction. The Version II Bar mounts by multiple bolts and the lateral and foe aft rigidity is greatly increased over Version I.

Cusco 22mm Rear Sway Bar (3-way Adjustable) - 02+ WRX
-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.
$155 shipped!!!
http://www.gruppe-s.com/Subaru/subsus/cus_sway.jpg

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.

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.

GD Vaned and Slotted 2 Piece Direct Replacement Rotors for 04/05 STi

In stock and ready to ship; the best bang for the buck 2-piece rotors!!

Gruppe-S is happy to announce that we finally offer some affordable 2 piece direct replacement rotors for the front of your STi! This actually started as a personal quest for 2 piece rotors for my own car. As my 04 STi sees about 20 trackdays a year, I wanted something that was substantially lighter than stock and cooled better than stock, while still being durable and problem free. Lastly, these rotors had to be affordable! I looked at several manufacturers initially but almost everything I found was either ridiculously expensive or was a compromise in quality and design. After looking at about 6 different manufacturers, I finally came upon these GD Vaned and Slotted 2 Piece Rotors. Upon looking at the features and the quality, the price was very impressive.

-Retains stock Brembo calipers
-6 lbs. lighter per rotor than stock (equivalent to a total loss of 60 lbs. on the front of your car)
-Aircraft grade hardware (non-floating design)
-Zinc coated rotors
-Vaned and slotted
-Track tested

I got a set to test on my own car and and after spending 2 days at Thunderhill Raceway trying to break these rotors, I can say these rotors are the real deal. Despite some problems with the initial bed-in (my own fault), these rotors preformed admirably and I'm very confident in their quality. They're not the only rotors that could have met my criteria but we believe they're the best bang for the buck 2 piece rotors out there. The handling and weight difference at the front of my car is so dramatic that I had to set my coilovers to the next lowest damping level. I have yet to take a pyrometer to the rotors but they held up fine after several laps of threshold braking into every turn that I had the stupidity to fly into. To boot, these rotors will fit both the 04 and the 05 STi! Here's the catch: we only have a limited quantity of these rotors available.

Here's some pictures of the prototype set that went on my car. *The actual rotors will have gold annodized hats to match your Brembo calipers.*

$579 Shipped!!!

Also as an introductory special, we'd like to offer a slight variation of the same package that I have on my car. This package is well suited to both daily driving and all ranges of weekend track warriors (who drive their street car on the track). This package speficially attacks all the weaknesses of the STi braking system while retaining it's strong points (the calipers). Stopping distance, fade resistance, and pedal feel are all dramatically improved. As these are carbon cermaic pads, they will require more effort to stop when they're cold but when they heat up, man do they stop! They're also quite quiet.

PACKAGE IT UP! - Pads, Rotors, Lines, and Motul!

-Endless CC-X Carbon Ceramic Pads - F
-Goodridge Stainless Steel Braided Lines - F/R
-GD Vaned and Slotted Direct Replacement 2 Piece Rotors - F
-2 Pints of Motul RBF600 Brake Fluid
$829 Shipped!!!

http://www.gruppe-s.com/stuff/Rotorpackage.jpg

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 03+ WRX - $319 Shipped

Special Brake Packages for the STi:

We all know that STi comes with awesome calipers but we unfortunately can't say the same thing about the pads, rotors, and lines. Sooooo, here's the stuff you really need!

Porterfield R4-S Brake Pads (carbon kevlar)- Front Pair - 04+ STi, F/R
These pads are a good balance between race pads and street pads. The Porterfield R4-S’ are unique because they’ll withstand 20 minutes of track time with no fade (they so not fade at temperatures up to 1,100 degrees F) but at the same time, they will work fine when cold and they’re very rotor friendly (as well as being very slow wearing). The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort. The R4-S compound also has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brakes material.
Good for autocrossing, drivers schools, weekend track sessions, solo events, and rallys.
$199 shipped for F OR R, $269 shipped for F and R!!!
http://www.gruppe-s.com/Subaru/subbrk/porterfield.jpg

Endless SSS Pads - 04+ STi, F/R
These pads are an excellent choice for the agressive street driver. They are non-metalic so they are rotor friendly and dust is minimal. The SSS feature a high friction coefficient so they are suitable for short weekend track stints but are not applicable for heavy track use.
$180 shipped for F OR R, $340 shipped for F and R!!!
http://www.gruppe-s.com/Subaru/subbrk/SSS+.jpg

Endless CC-X Pads - 04+ STi, F/R
Proven to perform well on both street and track conditions, this original formula, ceramic carbon metal base compound has the ability to perform for a wider range of users. For the street where low temperatures are frequent, this pad performs well causing less damage than most semi-metallic pads. Usually, semi-metallic pads sacrifice initial response to perform better at higher temperatures, but the CC-X is able to do well at initial response as well. At higher temperatures, pedal feeling responds well while maintaining controllability with a stable coefficient of friction.
$250 shipped for F OR R, $435 shipped for F and R!!!
http://www.gruppe-s.com/Subaru/subbrk/ccx.jpg

Endless Stainless Steel Swivel Brake Lines - Front+Rear - 02+ WRX/ 04+ STi
The fitment portion of the Endless Swivel Steel Brake Line includes an original swivel mechanism that allows for spinning to reduce tangling and decrease chances of breakage. This swivel mechanism can also be securely locked into place as well. Brake hose material is made out of a teflon tubing covered with SUS 304 stainless steel finely knit meshed blades. Additional black clear coating finish for protection against mud, gravel, cracking, and debris. Suitable for all seasons. Match and fitment test performed on each vehicle application to determine optimal hose layout for easy to use, correct installation.

Tein Pillow Ball Mount Subaru WRX GDA (front) 2002 (includes Wagon)

TEIN's pillow ball (spherical bearing) upper mount is designed for each individual model of the vehicle. By remaining the positioning design of upper spring and shock absorber close to manufacture's standards, TEIN's pillow ball upper mount keeps height change to the minimum and maintains the stroke center.

# The rubber bush is replaced with a pillow ball which eliminates the load input compliance, reduces the change of alignment to improve the grip of the tire.
*NMB's (The world's top spherical bearing manufacture) pillow ball is used.

# Ultra duralumin A2017S-T4 (aircraft material) is used for upper seats and adjusting plates with anodized aluminum to have maximum strength and durability.

# For the Mcpherson strut suspension(only for front) models, the camber angle is adjustable. This creates wide varieties of different suspension settings according to the road and tire conditions.

# High tension material S45C is used for serration bolts. As it is already inserted with high press, installation time has been completely reduced. With the original long bolt design, it can be easily mounted and gives enough thread for the strut tower bar to be fitted.

Why are your DNA springs 8/6? Did you special order them? The Helix website says they come 7/5 default.

how often does it (helix DNA series coilovers) need rebuild?? the cost of rebuild?

Are these available for an 05 STi?

Why are your DNA springs 8/6? Did you special order them? The Helix website says they come 7/5 default.

7/5 is what is listed under Synic MotorSport's thread for the coilovers.

Yeah, I know. I was the one to ask them if THEIRS was right too. :)

Gruppe-S? Any word?
