I just put a similar clutchnet clutch & Primitive flywheel in my 1997 Impreza (cable style). There is an adjustment at the fork under the hood, however I maxed mine out. It engages about 1" from the floor however I've noticed that is snaps in quickly to about 85-90% engaged, then takes about another .75" to fully engage. I'm worried that my clutch cable (car has 120k miles on it) is stretched so that once wear occurs, I won't be able to fully disengage it... To aleviate this I'm planning to invest in a new one. Also there may be an adjustment at the pedal, however I haven't taken the time to look yet.
When my car has warmed up a lot, the clutch engagement point seems to move up the pedal some, but not more than .5-.75 inch.
Good luck with your problems... hope they get sorted for you.
I'll let you know if I find an adjustment on the pedal. I'll be putting my new pedals on this Friday and will look.. may take a gander tonight as well.
Thanks - Jon
