On my 86 5 speed its waaay at the bottom, just after you start coming up from pushing it down all the way. Is that a sign of a clutch without alot of life left? I thought the opposite would be a sign of that. It was like this when I got it, I have since replaced the slave, master, and got an adjustable banjo (to fix other issues) but it still enguages waaay low. It works, but is odd to me.

Since I rebuild mine and did my power bleed with the air can mine starts about 3.5-4" from the floor.

(izzy 4sp 3.4 with 88 2.8 flywheel )

My 86 GT 4spd is like that too, when i bought the car, my mechanic looked over it and said the clutch was still pretty good. I've always found that normal and new cars strange and confusing because you had to lift the clutch pedal so much before it would engage

When your clutch and throwout bearing start to wear it takes further and further down to engage the clutch. Since they wear thinner it just takes more distance to move it.

Ummm, no on that last post. the slave will not compress with an old worn disc, so it remains further out. the purpose of a hydraulic system is to remain constant.
A brand new clutch will actually have the fingers further depressed on the pressure plate, thus being further away from the rest position of the throwout were it retracted all the way. as the clutch wears the fingers come out further, thus the distance from the fully retracted throwout bearing is shorter. To keep the pedal more consistent, the slave does not compress more than the fingers push the throwout back, hence there is always light contact with the throwout bearing and the pressure plate fingers.
the pedal position is a function more of either the pedal being slightly bent, or minor leaks in the master causing more travel to be required to get the same fluid volume moved to the slave.
bottom line is if it is working, ie fully disengaging and engaging, then if you are smart, leave it the f* alone.

forgot to add, both my 86 an 88 are almost identical, engage is about 2" from the carpet. and that is just starting to engage, as in uphil, you won;t go foward, but there is slight engine load. full engagement is about 4-5" off the floor, never measured it. full disengage in order to get into first or rev is basically 1" to floor board (or less) to be sure.

1987 GT 5speed. I can lightly rest my foot on the clutch pedal, pedal down maybe half an inch and I can shift gears.

i'm sorry to say you will probably be replacing your clutch sometime soon.
or you're really good at matching the engine rpm with transmission input rpm

That makes sense. I have to vehicles that the clutch doesn't fully disengageby the time they hit the floor, so I was thinking the clutches were going out. The must have air in the lines.

on my 88gt the stock clutch dissengaged near the top (about 1/3 down) and it was in good shape, then i put a centerforce dual friction clutch in, brand new, same thing about 1/3 down. Then i put in the spec stage 3+ clutch with the spec alum N* flywheel and the dissengagment was right on the floor, It sucked big time so i took out the getrag slave cylinder and put in an isuzu, brought the pedal up so it dissengaged about 1/3 down again, made the pedal effort a little more but i like haveing a stiff clutch. I hate clutches that are so light it feels like the pedal isn't connected to anything.

SO sounds ok for my Fiero. However my '93 Frrd Ranger 5 speed's clutch might not last (ouch). All the shifting takes place right on the high end of the pedal.
