Does anyone know if it possible to install 997 S clutch in a late model 996? The 997 S pressure plate has a self adjust mechanism which compensates for wear of the clutch disc. This is a nice feature since the pedal effort remains constant over the life of the clutch.

Quite simply no it does not fit. If you laid them next to one another you will notice the 997s has the pressure ring is extended out of the housing quite a bit, this requires the flywheel to mount basket style where as the 996 is flat.

yes, the pressure ring extends out of the housing compared to the 996 pressure plate. However, you will notice that the 997s flywheel has a raised portion where the pressure plate fastens to it. This compensates for the difference in the pressure plate. The attached images shows the difference between the 996 and 997s flywheels.

Therefore, it looks like to use the 997s self adjusting pressure plate it must be used with the 997s flywheel. Then the question is whether the 997s dmf will fit the 996. Does anyone know?
