I think the ACT XTSS feels just like stock engagement to me.

 

yeah you get so used too it i loved my hdss, gona xtss next, it'll handle mostly anything........

 

are you guys running solid or sprung six pucks?

 

either it wasnt installed correctly or you just dont know how to drive. I have had my act hdss for 2 1/2 years and the entire time ive had 400+ hp

In the last 6 months this clutch has seen my 35r and meth with atleast 45 launches on it and tons of street abuse. Ive actually been trying to burn it up since i have a new clutch waiting to go in.

 

Sprung 6puck

 

xtss just installed in my car approx, 1k miles...pedal is hard

and shifting is notchy on spirited driving to the point wont engage fast.

 

The ACT locked me out about 90% of the time when I was at the track. Do it right and get the twin.

 

Adjust the XTSS, I had a HDSS and I could shift at 8000 NO issues, what so ever. Loved that clucth, never once caused an issue.

 

This is my second Act...and having same problem. Ont the other hand my Rps 6 puck did very good.

 

im still on my act hdss, but i have a xtss with a solid hub 6 puck waiting to go in...

 

just an update, i made 504whp and 456tq with the hdss. still holding strong.

 

I'm about the put the ACT Extreme in; I had the ACT Heavy duty for many miles of spirited driving and loved it. Once the clutch rod was adjusted it worked perfectly w/ no lockout. I'm looking forward to seeing how the Exteme holds up.

 

same here im going with the xtss with my 35r setup

 

I hear from very reliable source the ACT clutch is very bad for your thrust bearing. It puts too much pressure on the crank all the time, minimizing the effectiveness of the lubrcant causing excessive wear. Too bad for me. I just bought one. Imma switch to an exedy twin plate here in a minnut. I only have 200 miles on this clutch but I don't want to kill my build because of something stupid like that.

 

Then I'd question just how reliable that source is . I constantly see different so called "experts/vendors" come up with varying opinions on products when it suits their needs. Unless you're driving a 2G Eclipse that is prone to crank walk that makes no sense. The only time the extra clamp load becomes an issue for the bearings is on cold start up.

If you're that worried about it disconnect the clutch switch so you don't have to press the clutch to start the car. Apart from that, once the engine is warm the only time your foot should be on the pedal is when you're changing gears. At that point the bearings should have sufficient lubrication, if they don't the clutch is the least of your problems.
