Arrow Big problems with Spec stage 2 clutch

I recently had a reputable transmission shop install a Spec stage 2 clutch on my 96 GT.The biggest problem is it only lasted 5K miles.
Since the day I installed this Spec stage 2 clutch it has made a
chattering noise,bucking on take off and between shifts,and when I took my foot off the clutch petal it made a kinda ticking noise.When
I put my foot on the clutch petal the ticking noise slowly went
away.I never seen or heard anything like it with this clutch.Also
the petal pressure was heavy and not very streetable or smooth
at all.The transmission shop I had install this Spec stage 2 clutch
took it all apart.The transmission techinican said that the Spec
clutch disc failed soon after all within 5K miles.I did the proper
break in of this clutch and after the break in I wasn't hard on this
clutch at all.In the past I heard of people having problems with the Spec clutches.What could of possibly happened to make this Spec clutch only last 5K miles? What clutch should I replace it with?
What clutch will last?

exactly how reputable is this shop? the "ticking" or chirping noise when your foot is off of the clutch pedal is the throwout bearing coming in contact with the fingers on the clutch itself. there is supposed to be a 1/8-1/4 amount of space between the throwout bearing and the fingers, and that chirping is from the fingers making contact. that improper clutch adjustment can lead to premature failure of the clutch, and can even ruin your transmission if left alone for long enough.

that might have been the culprit for the chattering and stiff pedal too, but with a more aggressive clutch you most likely are going to get a stiffer pedal feel and it might chatter too. my fidanza 2.1 chatters a bit once the clutch gets heated up going from a stop to 1st, but it's something i'm fine with considering the clutch is substantially stronger than my stocker. it's rated to 497lb/ft of torque.

The transmission shop I go to is very reputable.They have done clutch jobs for four of my friends and they all have Ford Mustangs.
All my friends recommend this place and they never had a problem with any of the clutches they had installed there.When I had my Spec stage 2 clutch installed they replaced the throwout bearing,throwout bearing retainer,stock OEM clutch cable,quadrant and firewall adjuster,pilot bearing,brand new Spec steel flywheel,
and the transmission mount.No,I have researched these Spec clutches and they are well known for making noise like chattering and ticking etc. Mine even bucked on me.They aligned my clutch
correctly using the Spec clutch alignment tool.The stock OEM
clutch cable was also adjusted correctly too.I extremely doubt that
my transmission shop made a mistake when they installed my Spec clutch.They installed four of my friends clutches and their clutches are just fine.Alot of other people have also had problems with these
Spec clutches.My Spec stage 2 clutch was stiff as a board and I
honestly hated the feel of this clutch.I'm convinced that Spec
clutches are inferior junk and I will never purchase a Spec clutch
or products ever again in my life.I highly recommend not giving Spec
your business after my experience with them.

Also for power I'm only making 215 rwhp and 280 rwtq.
The transmission shop manager and owner were both
mad and they said that they will never install a Spec
clutch or product for another customer ever again because
they don't want their shops reputation to be ruined
because of Spec clutches.

I think I will really like the Centerforce clutches.
I have read excellent reviews on the Centerforce clutches.
I just ordered a Centerforce dual friction clutch and
Centerforce steel flywheel.

I got a great deal on my Centerforce dual friction clutch
and flywheel from a vendor on eBay.I guess it pays to
shop around.

If your hearing a sort of noisey squeaking sound coming from
the transmission area your throwout bearing is probably prematurely
failing.For the time and labor it takes to replace just a throwout
bearing you mite as well replace your clutch also.You should definitley look into getting that fixed soon.Get a stronger aftermarket clutch to replace it with.Whatever you do don't
get a Spec clutch they are inferior junk.

your clutch may just be out of adjustment. take the dust cover off on the transmission under the car and take a look inside. i bet the fingers on pressure plate are coming in contact with the t/o bearing. if so get yourself a firewall adjuster and make it so the fingers are 1/8-1/4 inch away. if they aren't touching your t/o bearing is going bad and you're going to need a new one.

How many miles do you have on your clutch?
Do you still have a stock clutch? Do you have a aftermarket clutch?

hey i didn't mean to cause any harm, i've had this problem for a while and the squeaking is just getting louder and it feels like my car is losing performance from it, if that is even possible. it seems sort of sluggish. here are all the specs for my problem.... i have 42000 miles on my car, stock clutch, i have a firewall adjuster, new clutch cable, and quadrant. *when i first installed the clutch stuff (cable, quadrant, adjuster) i had it tightened up pretty good. the clutch would engage like two inches from the pedal being completely out. i then realized, after a couple weeks, maybe 3, that it was way too tight and loosened it. the pedal would sort of vibrate a little bit when loosened (screwing IN the adjuster) and it didn't catch well. during all of this, the clutch pedal would feel like there is stretching or it scraping something, and it would feel horrible. recently, the clutch pedal movement has become smooth again, but the throwout bearing, or some bearing is squeeking and making noise when i'm driving. when i push the clutch pedal in a little bit, the noise goes completely away. like if i'm in 3rd gear at like 30 mph in a tunnel, i can hear a loud squeal along with exhaust noise (my exhaust is kind of loud) so if i can hear it over or with my exhaust, it has to be sort of loud. anyway, the car now feels slightly sluggish, but it might be my imagination. last night i loosened the cable a couple clicks (screwing IN the adjuster), and the car almost feels slightly quicker, but there is still the noise.

hopefully that is some good info. someone on another thread said to look for some grease inside the dust cover somewhere, should i try that? this might sound incredibly stupid and forgive me, but a tad bit of wd-40 on the bearing? forgive me... but i just had to ask

should i screw in the adjuster all the way and see if the tob has the right gap? **when i look into the dust cover and see everything spinning, the tob is spinning also, at idle. at idle i can hear the squeaking noise also.

this is really scaring me now that i saw it could damage the tranny. it's been squeeking since may. please help...

How are you calling a rookie asshat? You need to stop trying to be
rude and asuming at the same time because I've been a Ford Mustang enthusiast for fourteen years now.
Time for a chill pill my friend, this site is about everyone getting a second opinion. And all evan was doing was trying to cut down on the amount of threads started on here. Everyone is pretty chill here so don't try and be billy bad arse up in here. And BTW 14 years in the Mustang business is nothing compared to some people in here . And as far as another clutch that will last well, you could try a King Cobra clutch. And if you're a Ford tech like your profile says, why didn't you install it?

Just a little FYI, at your power level a stage 2 clutch isn't a good idea and is probably contributing to the early failure. That and driving. You'd be much better with a lower rated clutch that has more predictable and gradual engagement.
