5.7.2. Clutch wear
It is possible to service the carbon/carbon clutch to achieve a longer
service life. To compensate for the carbon disc wear compensation
pressure plates can be fitted. By using thicker pressure plates it is
possible to return the clutch to its initial condition concerning the position
of the diaphragm spring and therefore the axial clamping load.
When your car is delivered additional documentation is supplied which
also includes a clutch data sheet. All the relevant setting and adjustment
data, wear thresholds and service instructions are noted.
