Starting today, my clutch is starting to engage as soon as the pedal is lifted from the floor, rather than about an inch or so that it usually takes to engage the clutch. Along with this, it is chattering bad and the pedal vibrates. I have a Spec Stage 3 Carbon clutch, just put in the car in January. What could this problem be? I am off work all weekend starting tomorrow and do not want to have to pay a shop to look at it. Any suggestions/opinions?

 

did it come with an adjustable slave?

 

I would say call Spec Clutch

 

It has a new slave cylinder and clutch master cylinder installed when I had the clutch put in and tranny rebuilt in January. Does anyone have the phone # for Spec if I need to call them? If necessary I will drop the tranny this weekend while off work to try to find problem. I hope it is just a throwout bearing or easier, because I have never dropped a tranny in one of these, like I said everything else, including pilot bearing was replaced in January. Any other suggestions/opinions?

Took out tranny today and guess what, 2 of the 6 springs on the clutch disc were blown out and 2 of the 4 others still in the disc were cracked. In January, the tranny was rebuilt, new clutch master cylinder, slave cylinder, pilot bushing, NEW Spec stage 3 carbon disc were all put in and 6 months later the clutch disc blows out the springs again? All of this with a stock motor on a clutch that is supposed to hold 680 ft/lb of torque? What is going on to cause this? Same thing happened in January when I replaced it before, 2 springs blew out, but had bad tranny bearings and pilot bearing then. What could be causing this and what do you guys suggest that I do? The car is a daily driven street car, no hard launces, no track time or street racing or clutch drops, so what is going on?

Might want to stay away from the stage 3 on a basically stock motor. my friend has something like that and he has to rev it up higher to get it to move... He cant stand it. maybe i was thinking that there is to much grip and its stopping the clutch basically in its tracks when you release it.. could that be? dont you have to rev it up more than you used to? that could cause a problem if its a street driver. I would have gone with the stage1 I have replaced my clutch 2 times and it has 80,000 miles on a 95 Z28. I always replaced with a factory replacement, nothing special and it does great, i have a modded Z28 with a every bolt on you can find, factory clutch still holds up.. i recently got the car at 60 from my relative so i have known it its whole life.

 

No you don't have to rev it to move. I am assuming that your friend may not be very good with a clutch or hasn't been driving one long. You drive it just like a normal clutch, it just grabs a little quicker and harder. MUCH more fun to drive, well when the clutch isn't blowing up I am going to call Spec on Monday about this clutch. Hopefully their customer service is as good as everyone on here says it is. I will probably downgrade to a Stage 2 however, so this doesn't happen again, hopefully it is just a bad design in the Stage 3 only.

 

Spec said some misalignment somewhere should be whats causing the springs to blow out. They mentioned bad engine mounts could possibly cause this, pilot bearing (I have a bushing in it now, not a bearing) or excessive runout in the transmission or input shaft. Their advice was to go with an unsprung disc = Stage 4 disc or correct what is causing the misalignment/vibration in order to stay with a sprung disc. Oh yeah, transmission was rebuilt in January because of bad bearings in tranny and the pilot bearing was destroyed.

 

I would check your motor mounts and also talk to the shop where you had the trans work done at. If your pilot bearing took a dump, that allows the disc to drag down the input shaft and can misalign and damage many internal components of the trans. Maybe they didn't do as complete of a rebuild as they should have, or just careless work. I wouldn't go with a stage 4.

 

I am going to go ahead and order a new clutch disc and have them send it on out to me. My question is what Stage should I go with? I liked the Stage 3, but I am worried about this happening again. I think that with as grabby as it is, if I went with a Stage 2 it might be a little easier on the springs, am I correct in assuming this? Stage 4 IMO would be too grabby for the car. What do you guys think?

 

I have a stage 2 and i am plesed with it. i only have about 300 miles on it so i am not even throught he trial period yet but i am very pleased with it.

 

Thats what I got....the stage 4 carbon.

 

How bad is that clutch in everyday driving? Would downshifting/engine braking help to cause this?
