Jimbo:
Cobra29 is right on the money in all aspects of your issue. The pedal ratio and comparative sizes of the master and slave are what will get this resolved. One item that has not been brought up is that when increasing the size of the master, a point can be reached (Fluid displacement) where the slave can be overpowered and the rod pushed out of the end of the slave and dumping all the fluid out. With careful planing this can be avoided. If this becomes a problem, a dimensionally longer (same diameter) slave will
cure this once the correct sizing has been arrived at. This is a OEM 289 push type setup, with the clutch arm pivot on drivers side, it works flawlessly. This is not a BDR car, but that really makes no difference. The components are working in harmony.
