What to do with ACT clutch?
I bought it brand new ACT HDSS w/ organic plate from another member on the forums, wanted something stock-like and non-noisy to replace my quartermaster. Sounds good so far, but ever since it has been installed, it has been slipping like crazy. I thought it was normal for the break-in process, but now that i am near 300 miles, it is still slipping. I did the install my self by following evomoto writeup.
Took almost 1 month to get the car running because i was searching for the mechanical clutch assembly. I had it looked at by a shop and they think its a defect unit caused by a bad pressure plate.
The engagement point is at about 1/2 inch down when pressing down on the clutch pedal, i have already adjusted the clutch pedal far out as possible. I have bled the slave cylinder numerous of times and the shop even did the same. Still slipping, any ideas?

I find hard to believe that a respected vendor hasn't release a single disk to compete with the PLAGUED WITH PROBLEMS ACT clutchs. Seems like people are having a hell of time with just about every non OEM single disk out there.
The only real choice is the exedy twin but it doesn't seem to last as long as most wish it would. It also has the circlip ejaculation problem.
Personally I've had great luck with the stock clutch. 1.6 short times and solid enough to provide 11's as well as firm grip for lapping day after lapping day. This leads me to believe the stage one may be the hot ticket for those around 400whp.

yeah, i regret not getting the stock clutch. this thing is a pos. engagement point too far out and its slipping like im driving a worn out clutch. it can hold first fine then 2-5 slips as soon as boost comes about.

I havent had any problems with any ACT clutches that I've owned. ACT in other car communities are very highly regarded. The only reason I didn't continue to use my ACT is im going to 700+whp and it simply wont hold that level of torque.
I think most ACT related problems are do to installer/operator error.

I would be glad to test the clutch for you to see what is going on. Torque capacity of a clutch is easy to calculate. If it is not holding, it should be easy to determine why.

Lengthening and shortening the rod will do nothing except cause the piston in the slave and master cylinders to be placed incorrectly for proper operation. A hydraulic system will compensate for longer and shorter rods without affecting pedal travel.
