looking at various clutch options and it looks like most of the higher torque rated clutches are not particularly daily driver friendly... at least not in stop and go traffic. So my thought is since the clutch is hydraulic, can a remote brake booster be used to reduce pedal pressure? Searching around google, it appears as though many have done this sort of thing but is more of a hot rodder modification. Given the simplicity of the setup, it would seem reasonable that it should work.
