Biggest, I've got a hydraulic clutch on my 1998 SVT Contour. No problems in 5 years, and it gets some abuse because the motor has no low end torque and my son learned to drive on it! Pedal feel is much better than on the Cobra. Only odd thing is that fluid reservoir is shared with the brake master cylinder.
but that is a frt wheel drive trans...NP Now with the pressures required for the clutch on a cobra, they would end up making it an internal slave and would probably have allthe concerns of the f150 hydro clutch(leaky, hard to bleed, trans rere to repl)
