SPEC Custom Performance and Race Clutches and Flywheels

SPEC Clutch Kits are the leader in aftermarket performance clutch with 8 stages (Spec Stage1, Spec Stage2, Spec Stage2+, Spec Stage3, Spec Stage3+, Spec Stage4, Spec Stage5, Spec Stage5+). Spec Clutch has a stock pedal feel with clamping power that is suitable for every application. Spec Stage5 performance clutches have been tested behind manual transmission vehicles with more than 1000hp and for less modified daily driven clutches, check out the Spec stage 1-3. The clutch kits include a high clamp load, quick release pressure plate, corresponding stage disc, bearings and alignment tool.

Made from high carbon steel or specially treated aircraft aluminum for superior rotational integrity and warp resistance, the SPEC billet flywheels feature a hardened replaceable ring gear, high strength racing bolt kit and SFI certification. SPEC flywheels are manufactured to an industry leading .001 inch. The billet steel units provide desired momentum for street, drag and large turbo applications, but weigh less than stock for greater reliability and noticeable horsepower gains. The aluminum flywheels are lighter for better performance at road race/Time Attack and autocross events.

Sequential Shifting System [SSS]

for STi 6 speed

Sequential Shifting System [SSS]

for STi 6 speed

The SSS is revolutionary patented design that converts the standard H pattern shifting, to a fully sequential shifting mechanism. It is an external attachment for your gearbox, which means there is no gearbox intervention.

Installing the SSS will enable you to:
-change gears without lateral movement
-change gears fast, smooth and accurately
-view selected gear on the Digital Indicator

Benefits and features the SSS has to offer:

-Quicker and accurate gear shifts aiding to reduce lap times and avoid mis-shifts.
-Easy view of selected gear on Digital gear indicator.
-Reverse and neutral safety lock to avoid shifting into the neutral or reverse gears during shifting into low gears. Option to maintain just reverse blocking only.
-Manufactured from a combination of nitrocarburised steel and AICu4Ti alloy for strength.
-Unique shifting solenoid (booster magnet) that allows significant time saving advantages when shifting and prolongs the life of the gear box under extreme usage.
-Will not impact the interior look of the car for a clean and professional finish.
-NO gear box intervention which reduces installation time
-Easy adjustment for fine tuning.

Basic Info

-The body of the Subaru SSS is placed in the tunnel next to the gearbox.
-The conversion is provided by a series of rods running to the body. One of the rods determines the gear lever position with the other one securing the change of gear.
-The whole mechanism (body, rods etc.) is protected from underneath by the skid plate.
-The SSS consists of a safety lock to avoid shifting into the neutral or reverse gears during shifting into low gears. The neutral and reverse can be only engaged if the safety lock is released.
-The SSS is also equipped with a shifting booster (magnet) which assists in selecting gears faster and easier
A Digital Indicator is supplied to view the selected gear.

Quaife ATB Differential for WRX

The Quaife is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits. The Quaife has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

In cornering, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.

The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement.

Performance Aluminum Single Drive Shafts for

02+ WRX, STi, Forester XT.

Description: Subaru GC8,RS,WRX and STI Aluminum Drive Shafts This is our 3" Aluminum single shaft for all the Subaru platforms. These shafts are in some of the fastest Subaru's around the world including Easy Streets WRX and Big Valleys STI. the shafts do have some clearance issues so the floor will need to recontoured a little (some floor braces flattened along with the floor you must have ¾" clearance all the way around the shaft in every area) these shafts are designed for street use but may also be used for racing, so we need to advise you the shaft has a 600WHP max and a critical speed of 150mph. These shafts have had more than both put into them but these are the recommended limits. This shaft is less than half the weight of the factory 2 piece and by eliminating the hanger will remove the lag the factory shaft has when the hanger moves up and down.

Please be patient, each transmission is Special Order and takes about 6-8 weeks.

Subaru STI 6-Speed w/ LSD & Adjustable DCCD- 02+ WRX : $8,499.99 plus shipping
The STI 6-Speed transmission was designed to handle the additional torque of a the 280HP STI, as well as the potential race modifications that the car may be subjected too.  Conservative at 280HP, many have subjected this transmission to 500 ft/lbs of torque abuse without suffering failures compared to high failure rate of the WRX 5-speed.  Designed  to address the weaknesses of the standard 5-speed, the 6-speed transmission is split transversely, instead of the longitudinal design of the 5spd. This design greatly strengthens the torsional rigidity of the case itself as well as the shafts and gears.   An added oil pump allows for better lubrication of the gears as compared to the "splash" lubrication system of the 5-speed.
