Spec 4F disk locked to flywheel for the 2ND TIME IN 2 MONTHS
The 2ND clutch I was told to put 1000 city miles on it before I raced. I put on 1200. Took it to the track on the Nittos and avoided the water box for a night per the SPEC recommendations. Put the ET Streets back on last night and took it to the track. 1st pass out it locked shifting into 2nd.
This time I knew what had happened. I managed to get into 2nd with a little rev matching and beat it a little. After getting into 3rd and jumping on it the disk broke free. Sounded like snaping a 2x4. That's when I knew the disk was free.
I have yet to test drive the car after this as I put right back on the trailer.
I'm done. 3 SPEC clutches in a year. I have about 20% of the total miles on my car into breaking in SPEC clutches.
Gonna go TH400 and be done.
Seems like chips from the edge of the disk are what is making them stick.
Looking for a TH400

I agree with some of the above posts. There are a lot of satisfied customers and all clutches seem to have issues.
But.....
I have had the trans out 3 times in a year changing clutches. My car had 17000 miles on it when I changed the first one and now has 21500 miles after all of the "break in" crap. I ordered this clutch as more of a race part than a street part. I expect it to work at the track, and be a little less than civil on the street. To date I have not been able to run the car at the track to it's potential. Its been a very frustrating season.
This is my .02, your milage may vary.
One more clutch issue and I will have built TH400 and be done!
Comment away...
. It sounds a little fishy to me that this is normal break-in (but I am not a clutch genious by any means). I guess I would take spec's advice and give it another try.FWIW, I still have not decided on a clutch for my car yet.
