I understand that the engagement is abrupt and the other 
"sacrifices"related to a racing clutch, I'm definitly willing to make 
the "sacrifices", but what my real question is.... It seems that with 
a self adjusting hydralic clutch, with wear & tear it will adjust 
itself. Therefor the point of friction or engagement when depressing 
the clutch pedel will move increasingly toward the top of the pedel.   
If the point of friction is ALREADY very near the top of my pedel, 
when my clutch self adjusts it will have no room to "go up"  This may 
not be an actual clutch disk problem, as much as a pressure plate 
problem. My main concern is clutch life.
