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.

STi Lightweight Flywheel

Lightweight (15.8 pounds versus 18.9 for the stock) flywheel is machined from high strength Chromium/Molybdenum. The reduced rotating mass will allow the engine to rev up faster.

Manual-Automatic Shiftronic Shifter Kit

Do you want to shift your automatic like a manual? Need to control torque converter lockup and shift firmness? The device that makes it happen is the Shiftronic Shifter. It's a plug-and-play module that mounts in the cockpit and links directly with your transmission computer harness to provide manual control of up and downshifts, shift pressure and converter lockup.

Once plugged in, you have the option to go to any gear you please, up-shifting and down-shifting when you want. The Shifttronic feature is great for drag racers, rally drivers and anyone who wants positive trans control. The controller also offers you the option of changing how hard the trans shifts, and allows the driver to lock the torque converter on deceleration for real engine braking-like a manual shift transmission.

Shiftronic also has the ability to switch from automatic to manual mode without unplugging the harness, switch operated.

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.
