Pics of everything we have done so far in case there are any questions about whether or not it was done right, you should be able to see in the pics.

The basic problem is this... installed a new SLP flywheel (never been used) and a new Spec Stage 4 clutch. We get it all buttoned back up, and fire it up. It sounds fine at idle in neutral. I rev it up a bit in neutral and everything feels good, no vibrations from the new setup, so thats good.

But the instant I depress the clutch pedal, I get an awful grinding sound from under the car. Well, we take off the slave cylinder to inspect, and the fork is obviously rubbing on the pressure plate somehow.

Additionally, when the car is sitting off, and you depress the pedal, it feels normal until the last inch or so near the floor, where it feels almost as if it is clicking or pushing through the slightest resistance.

We tried to shim the slave cylinder away from the fork a little bit, with no luck. We tried to reseat the fork, no luck. We looked at another M6 car and the fork seems to be resting in the bellhousing the same way. We just cannot understand why the fork could possibly be rubbing the way it is.

Help!

 

Any help would be greatly appreciated, as we will be tearing it back apart tomorrow. I've read that some people grind off 0.05" of the t-stud for the fork to fix this? Will this fix the problem, or is there somethin else to look for?

In short, the fork was rubbing badly on the pressure plate so we ground down part of the "T mount" and the fork itself and the problem was alleviated completely.

 

how is the clutch working on the street?

how was breakin?

 

I've got maybe 20 miles on it so far, and its still amazingly harsh, but its toning down at a fairly respectable pace. When I first tried to pull it out of the driveway after the install I thought I was never gonna be able to move it. If it keeps toning down at this rate I don't think it'll end up being too bad on the street. I could continue driving it at this level if I had to, but I think it'll get better.

(Keep in mind I am also using a lightened flywheel)

 

Do you mind updating me on how the clutch drives now? How hard is it to push down the clutch pedal? Can you rate the aggressiveness of the clutch when trying to slowly pull away from a traffic light?

 

i'm very happy with my Spec 4, i can count the number of times i've gotten audible chatter on one hand out of 100 miles of driving.

it's a little touchy pulling out from a stop, but like Head, i've got a light flywheel...even lighter than his.

so far very happy with the clutch, but it's still being broken in.
