I was interested in finding out more info on our "self-adjusting clutch"....


EXCERPT FROM ABOVE LINK:
=====================
Dual-Mass Flywheel
The dual-mass flywheel is designed to absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle. This is achieved by splitting the conventional flywheel into two sections: a primary section, which bolts to the crankshaft, and a secondary section, onto which the clutch is bolted. The primary section of the flywheel contains springs to isolate engine vibrations and a torque-limiting device to prevent engine torque spikes from exceeding engine and transmission component strength. When torque spikes occur, the torque-limiting package allows the primary section of the flywheel to turn independently from the secondary section, saving the driveline and transmission from damage.

Self-Adjusting Clutch
In conventional clutch designs, pedal effort increases as the disc wears. The self-adjusting clutch was designed to keep pedal effort low and constant over the life of the clutch. This clutch design contains a spring-loaded, self-adjusting wedged ring. As the disc friction material wears, the wedged ring in the clutch adjusts for the wear. A special disc design contains a double layer of marcels. These act as a spring to help lift the pressure plate off the disc. In addition to increased driver comfort, another benefit of the self-adjusting clutch is that it eliminates the need for periodic release system adjustments.


Keyhole Clutch
The keyhole clutch design features a spring-loaded tab cut into the clutch cover. Tension on the tabs automatically compensates for slack in the clutch, occurring over its life due to wear between the diaphragm spring and wire ring. By automatically compensating for wear, the keyhole design reduces the chance of clutch failure due to no release.



Series Damper
Recognizing the dual-mass flywheel was a complex and rather expensive solution to the elimination of gear rattle, LuK engineers designed the series damper disc. This design moves the dampening function out of the flywheel and back into the disc. The series damper contains two rows of coil springs, which compress in series; first the outer springs then the inner springs. The series damper eliminates transmission noise and gear rattle.




Extruded Hub Disc
Two of the most critical components of the disc for durability and performance are the flange and the hub. These are the disc components that transmit the engine torque, the parts that get the most load. In conventional discs, the flange is manufactured by machining a casting. In the extruded hub disc, the flange is produced with a stamping which extrudes the center hub by forcing it through a die. This process produces a disc that is stronger than conventional discs. The extruded hub disc offers increased durability and is designed for heavy-duty, high stress applications.


Modular Clutch
The modular assembly consists of a clutch, disc and flywheel riveted together to create a single, balanced unit. LuK's modular design reduces installation time and eliminates the possibility of contamination and misalignment during installation.

have you thought about Clutch master all the big boys on the NIRA circuit run Clutchmaster(and theres like 5 stages of clutches so you don't have to buy as aggresive clutch as they have)
also another one is Centerforce
