when i bought my gt used the clutch already came in with a firm clutch, over time i started to notice looseness at the beginning of pressing it in and figured it was worth getting looked at, the mechanic said it was time to get a new clutch so i forked over the money to get a new clutch kit. i figured when the new one was installed it would just go back to the same firmness that i was always used to but when i drove it out of the ford dealership parking lot i was amazed at how little resestance there was when pushing it in and easing off it, this made for faster shifts and overall better performance and i loved driving it again. unfotunately over time (about a week) the clutch went back to it's normal stiffness and i don't like it, is this normal? are all mustang clutches supposed to be stiff like this or is there simething more going on here?
