Just had a spec stag 2 installed at a vendor on this forum I don’t care to mention;

First thing I noticed was how hard it was to depress the pedal. It is about 3 - 4 times harder than stock; my wife can’t even drive the car because of it. Mechanic says, it is suppose too be harder to shift cause it’s a high performance clutch.

Secondly, when I begin to engage the clutch it feels like it is falling apart due to the vibration. The vibrating is so intense; you can see the rear tire shaking. Mechanics says it’s because it’s a Teflon clutch, or something like that and you can’t feather the clutch in, you have to go straight to engage.

Finally, it is very difficult to go into reverse, if at all. I have to shift from 1 to 2 before even attempting, and even at that it won’t go sometimes. Mechanic doesn’t have a response.


During installation mechanic put it all together and the clutch would not disengage. He pulled it apart and put it together again, but again would not disengage. He then called SPEC who said to use a shim somewhere in the clutch assembly. It will now disengage, but as you can see I think there are issues.



What would you do??????????????


By the way, my car now needs to be repainted because he left it under a pecan tree for 2 months before working on it and to add pain to insult the check engine light I paid him to fix, well.....it’s back on.

 

I just had a SPEC stage 2/3 hybrid clutch put in my car. The pedal feel is near stock. I had quite a bit of chatter at first but now it is mostly gone. I only have 175 miles on it so it is not broken in yet. With mine if I slip it slightly more than I normally do I have no chatter at all.

If you are having time getting it into gear my guess would be that the clutch is not completely disengaging when the pedal is depressed.

 

I have installed many of the SPEC assy's and there seems to be some variance in assembled hieghts that SPEC doesn't seem to feel like addressing. I love the clutches they make except for the pedal height issues. Typically when you are dealing with these pedal hieght issues, the McLeod master cylinder ( 1/16" larger bore diameter ) will fix the problem. I know its a PITA , and I am sorry you are dealing with this. I would call Jeremy @ SPEC tomorrow morning and tell him of your pedal hieght issues. They have been telling me that the Corvette applications do not require the shim behind the clutch actuator assy, and I have to make a special request for them to send me one on every assy that I purchase. I have had more problems with the SPEC 2+'s than the 3's, I never install just a stage 2. Stage 2 is Kevlar/Kevlar, 2+'s are Kevlar / metallic and 3's are metallic/metallic. The stage 2 should be less chatter prone than any of the discs with any metallic linings, although even with stage 3's I haven't had any real chatter problems.

Question for you.......Did you just by a disc and a pressure plate, or did you buy a whole assy including a flywheel ????? I have always bought the whole assy with the flywheel, because the whole assy comes zero balanced.

Do the master cylinder from McLeod, it will correct the low pedal hieght gig.....plus which the entire car will not have to be disassembled to install the mastercylinder.

 

Thanks for your response. Truth is I don’t know what exactly was replaced. I know I wanted a clutch flywheel package, but lucky me the mechanic decided I didn’t need it even though I paid an arm and leg for the install.

I will call him and get his opinion.

Thanks!!!

 

I just put in a Spec 2 clutch with flywheel (entire assembly) and it chatters a lot in reverse and a bit when going forward. How long does it take to break in?

 

They should be fully "broken in" by 400-500 miles of city driving

 

Don't mean to hi-jack your thread, but I'm having problems with my Spec Stage 2+ also and it sounds like RAFTRACER may be able to help me out. I have a Spec stage 2+ installed on a Fidanza flywheel and I'm having problems getting into the forward gears and reverse is almost impossible. My pedal engagement point is also right on the floor. The installer is looking at one of two solutions:
1. installing the spacer or
2. using an adjustable master cylinder for more throw and adjustment of the engagement point
My questions are:
1. Will the spacer put the throw-out bearing too close to the pressure plate?
2. If I use an adjustable master could that possibly cause an "over-reach" of the throw-out bearing?

Thanks,
Greg

 

About 500+- miles. Mine has a little over 500 and the chatter is all but gone.

 

I've had a stage 2 for maybe 15k miles. Lately I've noticed a low petal engagement and sometimes hard to shift into R. I have never had any vibration or tight petal problems. At the time of install my flywheel and clutch were replaced including the throw out bering.

How much did they charge you? I paid about $1600 including parts about 2 to 3 years ago.

 

I didn't see how old this thread was. Did you get your problem resolved?

 

Im having 2 out of the 3 problems you described... super tough to get into reverse..pedal is screwed up.. engages 3/4 inch from top of petal movements.. not fully engaging and now its burning itself down..working on a home grown adjustable master to see if that fixes anything
