SPEC CLUTCH KITS 996 C2/C4 '02 thru '04 3.6L
DUAL MASS FLYWHEEL / ALUMINUM FLYWHEEL
The car has a dual mass flywheel from the factory. If you're still using it, then select the standard stage kits. If you're using a light weight aluminum flywheel, then select the "for/ALUM FLY" kit.
The ALUM FLY kits have a slight change in the Pressure Plate pivots that puts the pedal travel back where it needs to be, and it comes with a different T/O bearing that is a different length to accommodate the thinner flywheel.
If you're still using the factory dual mass flywheel, then you can only use a solid hub (center) clutch disc. If you're using an aluminum flywheel, such as the SPEC or Fidenza, then you have the option of using a sprung center hub disc or the solid hub disc. The sprung center hub disc with an aluminum pressure plate will give you smoother engagement. A solid hub disc with an aluminum pressure plate will be a harsher engagement.
