Why create horsepower, just to lose it in the translation?

It makes no sense to boost engine performance like crazy, only to have the power dissipate as it moves back through the drive train. Yet that’s exactly what can happen with weak and inferior clutch/flywheel systems.

To resolve this problem, Active Auotwerke sought out the sources who make clutches for Formula 1 teams in Europe. (We love aiming high.) The result is a clutch system that handles anything you throw at it – including power up to and beyond the 600 HP potential of a performance programmed S54 engine. Yet retains the civility you need for everyday driving.

CLUTCH DISC
Unlike the solid factory clutch disc, our performance version uses a series of springs to effectively dampen gearbox chatter. An organic composite lining delivers baby-smooth engagement and transition of power, and is easy on the flywheel face.

PRESSURE PLATE
Our pressure plate has true racing heritage. Pedal effort is a tad strong (most noticeable on 6 speed versions) but is probably unmatched in its exertion of clamping force. A sturdy strap design and precision engagement clearance and balance characteristics round out the design profile. This high-performance component is fully compliant with factory specs, and can be used without changing out the stock steel flywheel, if desired.

ALUMINUM FLYWHEEL??
The physics are beyond question: reduce flywheel weight and you noticeably increase acceleration. So when we tell you our 6061 T6 tempered alloy unit tips the scales at just 12 lbs vs the 42 lb stock flywheel, you can imagine what performance gains are in store.
Yet, weight alone is just part of the equation. Durability is also key. Our patent-pending retaining pin design totally eliminates the common problem of pin disengagement in aluminum flywheels – a failure that can cause major damage to your transmission bell housing. Ideal for both street and mild race use, the quicker throttle response and perfect balance of an installed Active Autowerke flywheel is easily felt in the drive. Machined to precise tolerances, the unit comes with a thick replaceable friction plate and correctly-configured ring gear for smooth starter gear engagement. It will accept either the factory stock clutch kit or an Active Autowerke performance clutch utilizing a sprung disc arrangement.


Key Features
CNC machined aluminum flywheel; 12 lbs and vibration-free
Correct teeth on ring gear ensure correct starter gear engagement
Smart-design pressure plate pins emgineered to never dislodge and damage transmission bell housing
Replaceable flywheel friction face
Applicable for SMG and 6-speed manual gearbox cars

Tested and proven to handle over 600 HP

ACPT carbon fiber driveshafts provide a special measure of performance and extra safety. Independent testing by a leading automotive magazine (Turbo, October, 1996) showed rear wheel horsepower gains of more than 5% with the simple switch to an ACPT carbon fiber driveshaft. This significant increase is primarily due to lower rotational mass of the driveshaft. Carbon fiber offers you more strength to resist extreme torque than steel with about half the weight. Just like the common use of lightweight clutch and flywheel units, a lightweight driveshaft allows more of you engine's power to be applied to the ground.

In addition to minimizing rotational power losses, the unique vibration dampening characteristics of carbon fiber also help improve power output. Engine builder are familiar with the power gains that high performance crank dampeners can provide. ACPTs carbon fiber driveshafts give you similar benefits by cutting power losses due to drivetrain vibration.

ACPT carbon fiber driveshafts are an obvious advantage on the race track; but they also provide the same benefits on the street in cars and trucks as well as in industrial applications. Many cars, pickups, and vans experience vibration problems and performance limitations with OE metal driveshafts, especially two-piece units. Dealers and mechanics around the world are discovering that the only sure way to cure these problems is to install a one-piece driveshaft from ACPT.
