Just how far does the throwout bearing have too go once it makes contact with the diaphragm to disengage the clutch? There must be a measurement but I haven't found one. You can't go over center with a Center Force because the weights on the fingers will contact the clutch disk first. That is from the Center Force diagnostics guide. I run a centerforce in my cuda and one in my SRT-10. Love the 'Cuda clutch hate the SRT-10. Difference? The 'Cuda is all manual linkage the SRT-10 is hydraulic.
