try to adjust the clutch pedal a little lower so that the disc sits close to the flywheel and that way you will prevent slippage of it,after that test your car in 5thgear at 2500rpm and hit WOT and when it hits full boost if your rpms jump without the car geeting moved then its your clutch

No! Any adjustment to the pedal is only going to adjust the pedal. All you are doing is increasing the freeplay on the M/C rod and shortening the throw at the slave cylinder. You are not making the clutch grab better or last longer. And by testing it to see if it slips you are going to shorten the clutch life even more.

I doubt if your ACT ruined the trans any more than most other clutches. On the other hand, improper adjustment (very common on the EVO) or bad driving will ruin a tranny quickly.

so how come aftermarket clutches need pedal adjustment?
you need to adjust the pedal a little higher so that the transmision works well!
also if you put a clutch pedal very low it can sometimes make the car roll even if not in gear please explain?

a friend of mine installed an exedy twin disc and his car would roll even when it wasnt in gear, we adjusted the clutch pedal and problem solved!
so is it the same when you have your clutch pedal higher maybe its slipping cause its sitting at rest far appart from the flywheel so please act man explain ?

It's pretty simple. The less freeplay the pedal has, the sooner the rod pushes on the piston of the M/C and the farther it will travel the piston so it travels the slave and ultimately the pressure plate fingers farther to release the disc sooner. But the same is not true going the other direction. If you have some freeplay at the m/c rod, any freeplay, there is no force being exerted on the fingers of the pressure plate and it clamps only as hard as the diaphragm spring will clamp onto the disc.

thanks act man my experience well with my stock clutch is as follows:
why is it that with use my stock clutch would begin slipping and ive adjusted the pedal at a lower point and it would stop slipping this is what ive experience and its true adjusting it wont make it grab harder but it did stop slipping so whats your opinion on this? you talked about going the other direction not true!
