I just installed the spec stage 3 carbon disc clutch kit. The first time I installed it, everything felt great. Then I remembered my engine was from an automatic tranny so I pulled the tranny to install a pilot bearing. When I pulled it, I discovered it already had a bearing so I just installed everything back on (only using this engine for a few thousand miles). Now eveytime I let off the clutch peddle, the whole car shakes like crazy. I think most people would say it's just clutch chatter from a new clutch, but you have to understand it shakes the whole car and feels like my headlights are gonna break or something. It doesn't do it as bad when I rev higher to start moving the car. Downshifting is the worst, it seriously feels like an earthquake

 

I've got the Stage 2 and I need to rev it abunch and release the clutch very quickly to avoid some fairly agressive chatter. Reverse I simply can't avoid chatter. So, when you say the earth quakes with the stage 3 i appreciate and understand. I don't know what you can do about it though.

 

The website claims street/strip compatability but I don't think that the stage 3 is really great for street driving. I've heard others say it is a realy bear to drive too. I would never put that clutch in a street driven vehicle. Maybe you should consider a stage 2 for a modified street car? Then again... I've never driven the stage 3 Spec clutch.

 

Really? I've heard that the stage 3/4 aren't too bad...

I can't remember where I read that though..

I may have to rethink my clutch choice.

 

Feels like a normal clutch to me. I have the six puck in, has about 80 miles on it and it chatters a little but its definatley streetable. It feels no different than another replacement clutch as far as streetabilty, but boy is it sticky.

 

Your problem sounds like the clutch was misaligned. If you had a lot of trouble putting in the transmission, its possible the clutch was in there moving around and could become loose. Your pressure plate bolts may not be torqued down at the same rate for each bolt. I would check your pressure plate bolts, did you tighten them in a star formation? Doesn't sound like you have a clutch problem if it felt fine the first time.

 

I've been using a Spec Stage 3 carbon 6-puck for about 5000 miles. It did chatter a LOT at first, but it slowly went away, and now it is just absolutely perfect! It doesn't chatter any more, but still launches HARD. It's broken in so well that I can let out the clutch slowly and get the car moving without even giving it any gas!

But it did chatter bad for the first month or so.

 

I have the SPEC stage 3 too and it chattered its *** off for the first 500 miles! Just come off it faster and stick it out cuz once you get it broken in you will love it! You will be the only one that can drive the car without killing it though. Also, just use high revs and feather it in reverse, as it will chatter forever there.

 

This is so true. My father in law wanted to move my car and take it around the block, tried to go in first 3 times and hated it. Bua hahaha. Next was my cousin, he wanted to go around the block in my car. He didnt get past the driveway . Sure as hell keeps people from wanting to drive your car .

 

I know a few people with Stage 3s and the chattering seems to go away after a while. I have a Stage 2 and mine has never chattered.

 

If it were me and the clutch was acting up that badly I would have flywheel resurfaced.

 

flywheel was resurfaced. WHen I installed the clutch I did use the star pattern for the pressure plate. It was something like 24lbs

 

Yeah I'm gonna go with the "just live with it awhile" to see if it calms down, mine chattered a bit when I got it in, I have the 6 puck, and after a few hundred miles it's not too much worse than stock, I mean you can tell theres a clutch in there, but no chatter... going forward anyway...
