Only ACT clutches experience this?

The reason I said I'd be worried if it were the stock clutch with similar problems, it could POSSIBLY be syncros going out and why you grind. Or the clutch is having problems fully disengaging between shifts. Could be a worn throw-out bearing. How I would fix it is first install a SS clutch line and see if that improves any, and then next would be to inspect the clutch itself. If it is a stock clutch, chances are it'll need replacing sooner or later anyway. Better to buy a new one early in the game.

the SS line will help the pressure stay constant, am I right?

when I took the pill out and installed the SS line on my '03, the clutch felt less "squishy & vague". So, an answer to your question would probably be yes.

OP, do you still have your clutch pill in place? The clutch will actually last LONGER with it removed, but it is much harder on drivetrain for launches.

Yeah, I think the high RPM lockout issue should be a sticky on here. It surprises me how many don't know how to fix it.

well the different "fix" methods dont apply to me... My problem wasnt a adjustment problem, it was act giving me some POS clutch that didn't fit right (see page 1)...
side note, the act clutch in my subaru just crapped out on me yesterday, one of the pressure plate arms broke and wouldnt let the clutch release... That's the 4th act clutch I have used that didn't last more then 20k miles.

burklow- I did not remove the restrictor pill, figured i didnt know enough about it so i left it alone. besides, id rather buy a new clutch than other various driveline parts i.e. tranny case...

drooke- i actually like the HDSS. its grippy and little over stock feel, its just this lockout problem that sucks. so hopefully this works it out...

The outer edge of the clutch disk hub and the hub springs had been slightly rubbing on the pressure plate when the clutch would try to release...
no more act for me!
Same here NO MORE ACT FOR ME

Sometimes it's better to pony up the dough for the expensive one the first time around like I did. I had to save for a while then found a good deal on here from one of the vendors (I think it was Chris @ Nolimitmotorsport). Either way I put the Cusco twin disc (same as Exedy, even has there name on the intermediate plate) and haven't had a problem since, that was almost 30K miles ago. A few hard launches, lots of highspeed high RPM shifting since then and it still feels like the day I finished breaking it in! You're pretty much gonna pay the same labor regardless if it's a twin or single. A good shop is going to take the flywheel off anyhow so why not put a twin in there and be done with it! And no my left leg is not bigger than my right!

You need to lenthen the rod in the pedal adjustment to give the clutch more travel. You might also try bleeding your slave cylinder.
